Electrical Short/wipers?
Posted: Mon Nov 24, 2003 11:29 am
Hi,
Your suggestions for fixing this one please!
Saturday I drove for about 1 1/2 hours through the appaling rain (here in the SE). I had everything going - headlights, wipers, heater fan, and radio - I had to listen for THE RESULT!
Just as I stopped in a side road, the wipers stopped working (on the full non-park position). I opened the bonnet (engine off, all switches off), and replaced the 35Amp fuse. When I turned the ignition back on, there was a noticable dimming of the oil/ignition lights, no movement from the wipers, and anothe blown fuse. Repeated with the same results...
After coming back from the shopping (about 1 hour), I replaced the fuse again, the wipers parked, and eveything came back (except the radio).
I then drove home (M25/M4) for about 1 1/3 hours - everything going (except the radio) without any further problems.
Is it possible for the wiper motor to have an intermittand short/ overheating that would cause it to short? That fuse has (IIRC) the indicators, heater fan and brake lights running through it - (Radio's connected to the other fuse).
There was/is some water reacing the boot via the rear lighting cables, but the bullet connectors are shrouded and anyway the lights were off when I had the problem second time.
It's a 1964/5 1098cc 2 door with an alternator - the only non-standard fitting is the radio.
Any suggestion taken seriously,
Colin
