Thank you Steve for the detailed information you provided with regards to the relay differences as it cleared up my understanding of the true purpose and functionality of the -101 20/30amp.

Indeed, Bruce echoed your statements concerning the fact that the early TR manuals contained many discrepancies, misinformation, etc. Apparently, FNA has revised certain parts of the manuals; and Bruce recommended contacting the local dealer and inquiring about same.

From your description, it appears that the existing -101s in the car are the safest bet for the time being, as they are working just fine.

Apparently, my TR's glitch lies in the auxilary cold start / air valves circuit somewhere. They become charged on their own at various times when the ignition is "off" and the car is not running. I've heard the buzzing sound from time to time, and traced it to the air valves (you can feel them buzzing). They will buzz for a few minutes and then stop for a good while.

It's not causing a problem per se, other than the fact that it is not supposed to be happening, and that it causes a drain on the battery.

JRV recommended checking all the relays / fuses first, and then go from there. The fuse panel was just replaced with a new one last year.

(It is a mucked-up point in a lot of the TR documentation, but) Not to worry Eric, since yours is working with the -101s installed all is OK. Either:

1. If it was really intended to have the -113 relays (there will probably be only 4 of the 5 metal female connectors inside the relay socket) so a -101 would look just like a -113 functionally, or

2. I know on the later US TRs (like mine) the -101 relay is the correct one as they use the 87a terminal to hold the fuel pump motor windings at ground when they're not "on" (i.e., the 87a terminal of the -101 relay connects to ground so when the relay is "off", the motor winding on terminal 30 is connected to the grounded 87a terminal).

My guess would be most TRs have the #2 set-up since it's a safety feature, but I've no evidence. You might see if you can determine how many of the female connectors are inside the R & T relay sockets (4? or 5?), but if it's working with the -101s I think you're safe to stay with those in this case.

Was recently checking out all the relays / fuses on the TR and noticed a disrepancy between the Bosch part #'s published in the owners manual vs. those in the actual vehicle (an '85 Euro model Testarossa).

In the following diagram, as depicted in the '85 non-US version owners manual, are the published relays:

85 EURO TR RELAY PANEL

While recently troubleshooting the auxilary / cold start air valves, and checking all the fuses and relays relative to the fuel system, I noticed that relays "R" and "T" in the above diagram are different than the relays in the car....

The manual shows:

"R" = Relay for R.H. fuel pump (Bosch 0 332 014 113)

"T" = Relay for L.H. fuel pump (Bosch 0 332 014 113)

The relays in the vehicle and the diagram printed on the fuse panel door show:

"R" = R.H. Fuel Pump - Bosch 0 332 204 101 (plugged in panel)

"T" = L.H. Fuel Pump - Bosch 0 332 204 101 (plugged in panel)

Where Bosch 0 332 014 113 is a 30 amp relay (used on most circuits including the aux. air valves), and Bosch 0 332 204 101 is a 20/30 amp relay (used for head lights / lift motors).

Hence the confusion. At this point, I'm not certain as to which relay is the correct one to use for the R.H. and L.H. fuel pumps -- the "204 101 ~ 20/30amp" (currently in vehicle) or the "014 113 ~ 30amp (as per owners manual)?

Have any other TR owners out there run across this or know which is the correct relay? Was curious what other owners have for relays in their cars. Was trying to nail this down before going relay shopping.

Thanks in advance for any help or ideas!
