I noticed that the Rh side was flashing the running lights so I decided to remove the housing and check the wires incase they where wired back wards. Everything looked good to the wire diagram you sent. So I got a test light and check the connector. Everything tested fine except when I check the ground wire the test light didn't light up. I attached a new groud wire and everything works great. This is the first time since I've owned this car that my signals work. Thanks for all the help. | ||

The TR turn signals flash the 21W single-filament outermost lamp and the 21W filament of the adjacent (center position) two-filament bulb (the 5W filaments in the center bulb and in the inboard smaller single-filament bulb are the parking running lights). The emergency flasher system just flashes all the turn signal lights together (i.e., the ones noted above, and, of course, the rear lamps too). | ||

Took the yellow lenses off the front to get a better look. There are 3 lights. The 2 outside lights are big 12v 21w with one filament. Next ones is also big with two filaments 12v p21/5w. The next two in closer to the grill are small single filament 12v 5w. Can you tell me which lights are suppose to falsh when you turn left and right. Also when you put the 4ways on. My left lights don't match my right lights when they flash. The lights on my RH look brand new. The lights on my LH have some acid build up on them. | ||

Do all the RH external turn lamps seem to light up properly when you make the RH current measurement? I don't really see how the RH current can be so low unless: a) some of the RH lamps aren't illuminating, b) incorrect wattage bulbs were used, or c) there's some extra resistance (a few ohms) in the PWB itself between the k connector male pin and the b and j connectors. If the RH side bulbs appear quasi-normal when lit manually with the current test, the only thing I can think of is to swap all the RH turn signal bulbs for the LH turn signal bulbs and see if the low current (and the "fast flash" problem) follows the bulbs. If the problem (and low current) stays on the RH side even after swapping all the bulbs then you might try making some resistance comparisons on the PWB -- RH side: k connector unplugged measure resistance from 9th male pin on k to 4th socket (light blue wire) on j connector measure resistance from 9th male pin on k to bottom socket (light blue wire) on b connector LH side: k connector unplugged measure resistance from that 8th male pin on k to 3rd socket (light blue/black wire) on j connector measure resistance from 8th male pin on k to 2nd from bottom socket (light blue/black wire) on c connector. | ||

Checked the amps and I get 5.72a on the LH and 3.45a on the RH. | ||

For reference, I just measured those currents on my TR and both are about 6.4A so make sure you get a multimeter with a 10A DC current capability. | ||

Just checked and emergency flashers work fine. I'll have to wait until tomorrow to buy an ammeter. | ||

Since your RH external turn lamps are also flashing (fast) with the RH dash turn light, it must be some other problem. Just as a (maybe related) side question, is your emergency flasher system working OK? Can you measure the current that each set of side turn lamps draws? -- i.e., unplug the k connector (and with a DC ammeter in series) put +12V from the battery directly onto the 9th male pin from the left (the one that would be hooked up to the two light blue wire if the k connector was plugged in). The RH turn signal lamps should all light up. Repeat the same measurement on the 8th male pin from the left (the one that would be hooked up to the two light blue/black wires if the k connector was plugged in) to check the LH side -- the currents should be about the same. | ||

I also put a test light on all the blue wires like you have listed for each side and it flashes just as fast and slow along with left or right signals. Everything seems to be hooked up right. I've also checked all the light bulbs to see if any are burned out, but they look fine. | ||

Just checked it out and with everthing plugged in. The left turn signal is ok and the right signal flashs fast. Both dash and external lights flash turning left or right. | ||

Luigi -- I was wrong. I just did the same test on my TR and the dash signal turn lights flash faster with the k connector unplugged (don't ask me why  ). The test results are: Normal condition ~13 flashes in 10 seconds dash lights flash and external lights flash together k connector unplugged ~28 flashes in 10 seconds only the dash lights flash (no external lights flash) Can you reconfirm that with everything plugged in you still have the same symptom: LH = OK RH = dash light flashes fast AND no external RH lights flash? If so, you must have an open circuit on the PWB so the RH turn signal command isn't getting from the k connector to either the j or b connector (the "j" connector is directly below the k connector and the "b" connector is the middle of the 3 vertical connectors on the left side of the fuse/relay panel near my hand in the jpeg). On a properly working system (with everything plugged in) when the RH turn signal is "on": The terminal in the k connector with the two light blue wires (9th position from the left), The terminal in the j connector with the one light blue wire (4th position from the left), and The terminal in the b connector with one light blue wire (the bottom position) should all flash together from 0 to +12V. Similarly, when the LH turn signal is "on": The terminal in the k connector with the two light blue/black wires (8th position from the left), The terminal in the j connector with the one light blue/black wire (3rd position from the left), and The terminal in the c connector (the c connector is to the right of the b connector) with one light blue/black wire (2nd from bottom position) should all flash together from 0 to +12V. Sometime LH/RH can get mixed up or just not be real clear on the schematics so I gave both sides for reference, but the bottom line is that all the light blue wires listed above should flash together for one turn direction and all the light blue/black wires listed above should flash together for the other turn direction -- good hunting... | ||

Pulled the K-connector and tryed my signals again. This time they both went fast. I'v had this problem ever since I had the car. I really don't know what speed they should flash at. Is the slow speed correct. Which is about the same speed I have on my other cars or is it supposes to be fast? | ||

If the right turn signal flash rate drops significantly (with the k connector unplugged) it can show that there's a short on the fuse/relay panel PWB. The RH turn signal line from the turn signal switch comes into the k connector on one of the two light blue (A) wires in the 9th position from the left on the k connector. Some current flows out the other light blue wire to some of the RH lamps, and some of the current flows onto traces on the PWB and then eventually off the PWB via the "j" and "b" connectors to the other RH lamps. If the the traces on the PWB is/are shorted to some other load, it increases the current draw and the turn signal flasher will flash more rapidly. With the k connector unplugged it takes the traces on the PWB out of the picture -- but it could still be something else (like a short at a lamp socket) so do this (easy) test first and we'll muddle from there. PS 1. The upper right relay is the "key services" relay so when you unplug that it's like turning the key off (which is why the turn signal flashing stops). 2. The third relay on the bottom from the right is for "flashing" the front passing headlamps (not turn signal flashing). I'm not sure where the turn signal flasher is, but I'd guess it's behind the fuse/relay panel. However, if your LH turn signals are working OK this indicates that the turn signal flasher itself is OK. | ||

Steve I'll try unplugging the K-connector tonight. What will this prove. | ||

I unpluged the relay in the top right corner and the flashers stopped. I thought the flasher relay was on the bottom row third one from the right? | ||

Luigi -- As an experiment, try unplugging the "k" connector (which is the upper left white connector at the bottom of TR fuse/relay panel) then with key "on" (engine off) see if the right side turn lamps behave better (some won't flash, but some still should). This jpeg shows the "k" connector unplugged on my TR:  | ||

When I put my left turn signal on it works fine. When I put my right turn signal on, it flashs vary fast. I tried changing the relay but its the same. Any suggestions would help. |
