Where the hells the earth????

Post by KarlT »

Hi All

Does anyone out there know where the hell the earth is on a caravelles electric front windows?

Hoping I've got a bad earth as have spent 6 hrs ( :roll: ) stripping,breaking,cleaning, re-fitting all the gubings.

Put wire straight from battery to motor & worked well.

But through proper wiring seem to run at half speed.

All help appreciated.

Have disconnected these two bundles behind fuse box but they still ran at half speed

An idea but....

I'd rather just find the earth, its got two motors & three switches. :shock:


It might of-course be a problem with the supply. It says 12volts but I'm not sure how to check if there is enough amps.

Yep, there's no point in worrying about earths if your 12V feed isn't up to the job!

You say it ran fine 'direct to the battery', so just connect ONLY THE POSITIVE side direct to the battery and see what happens. (Obvioulsy leaving the 'normal' wiring in place on the negative side!)

If it runs half-speed you do indeed have a poor earth. However, if it runs at full speed then your 12V feed isn't up to scratch somewhere.
