Please Help

All is disconnected, only wiring left now and still 1 ohm. What you can try if you can connect the ohm meter to the pink wire and ground by clamps so you can perform a continuous measurement. If you place your meter on your windshield you can see the value. Now try to push and pull on the cables and connectors and see if the value changes (higher or lower). What puzzles me is why there was an infinite reading yesterday.

 

Have a good lunch! All measurements should be done between ground and the pink and pink/yellow wire which were removed from connector J. No other measurements are necessary yet.

 

The spade with the pink and pink/yellow wire should be hanging loose.

 

And when you disconnect all the connectors (the three from the instrument cluster (buttons, lamps and clock), the two connectors of the electronic unit and the black connector from the check control. Do we have infinite then?

 

1, is that exactly 1 ohm or is it like 0.95 or 1.05? Are there more digits? Some meters will display a '1' when the value is out of range.

 

Ah, that's infinite and good!

Now you can reconnect the electronic device only (all other connectors disconnected) and measure.

 

Then reconnect the black connector of the check control and measure.

 

I misunderstood the '1' in all previous post, i thought it was 1 ohm, this is nearly a short

 

The zero, does this have more digits and what is the range of your meter (ohm, kohm)?

 

Ah, that's not good, should be in the ohm range! For example if you measure 0.12 kohm then it is actually 120 ohm and your fuse won't blow, if it's 0.12 ohm your fuse will definately blow! Your meter should be in the ohm range.

 

No, maybe we can use this one! But all the digits are important now.

First put the two probes together and record the value on the display, like 0.012.
Second, if you perform a measurement then record the value.
Calculate second value - first value, this is the measured value.
