Hi guys, I have almost finished re-building my sapphire cosworth 4x4. Before taking apart, all the electrics worked.

I have only taken the loom out and put it back in again, and now the wipers will not work at all, neither will the headlight wipers or the washer pumps. I am thinking supply problem? Fuse is however ok (checked with multimeter)

Another niggly fault which was there before is on the lamp failure unit, the rear light warnings are on (although they work) and one headlight warning is on (it also works) and also the handbrake light is always on regardless of whether the handbrake is on or off?? These little faults were there before but I thought that taking the loom out and cleaning all the earths etc up would fix these - it hasn't!
