Major wiring issue!

[Paul F]

I've got a bit of a wiring issue on my Escort... I've put the loom back in after a full strip down, I've got an ST170 engine (ECU not wired up yet), I've wired everything up that I can think of, checked all the earths and not much is happening.

 

I can get the engine to crank from the key, but with regards to any of the other accessories it's a bit rubbish! The front left indicator is constantly on when in ignition position 2, the hazards work at the front, but the n/s rear brake light and reversing flashes instead of the rear indicators. And that's it! No wipers, no other lights, no interior fan! I also don't have any ignition light. I know it's probably not one simple issue to fix and that I'll probably need to get someone to look at it, but can anyone offer me any advice?

 

The only adaptations I've made to the loom is extending the alternator and water temp gauge wiring. I've got an alternator from a Fiesta diesel - this had the same plug as on the original Escort loom, I assume that shouldn't make a difference?

 

Thanks

I had something similar on my fiesta. Turned out to be a bad earth to the body shell. Give um a good check ensure there is no paint or corrosion under the terminals

What age is the car ?

 

Normally there is a feed that goes to the fusebox & ignition switch from the starter or solenoid ?

 

The hazzard fault sounds like bad earth for the rear light units again some earth through the light unit some have a wire that bolts to an earthing point.

 

The fuse holders play up also so might be worth cleaning the connections.

 

 

Any earth points need the paint cleaning off to bare metal before you fit, you can apply some greese or similar to stop any rust afterwards.

 

The faults you describe could be a mixture of the above, check the obvious 1st

Thanks both for your replies.

 

It's a 1980 mk2. Have swapped over the plugs that go to the fuse box and there is now an ignition light! I think all terminals probably need a good clean up and I'll clean up the earthing points as you suggested.

 

Thanks again
