1970 Loss of Turn Signals, Help please

Postby colchester1978 » 22 Jun 2011 10:57

Hi

Please can someone give me some pointers as to why this might have happened? :(

The turn signals kept blowing the fuse which then burnt out the turn signal/hazzard switch in the steering column, I have since replaced this and both the 4 way Hazzard & 3 lamp turn signal relays but still no turn signals, everything else, front/tail lights, brake & Hazzard lights all flash fine. All fuses are fine.

Hopefully this is a common problem that someone might know the cause?



Cheers

Blowing a fuse usually means that a wire somewhere is shorting to ground. Maybe in the column but it could be anywhere like at one of the lamp units.

If it would blow no matter which way you were indicating or if it was blowing without indicating at all then the fault has to be the supply current from the harness into the column.

The wire may have burnt out completely due to the short. In which case the fuse would stop blowing.

Oooh! Good point! I forgot a sparking bad connection will kill a fuse too.

Yes your right someone had done a dodgey rewire job in the column which lead to a bare wire shorting out, I guess the damage might have already been done then as replacing this indicator cam/hazzard board hasn't solved the problem plus the new connector block at the end of this doesn't quite fit the other end of the dash harness block, the joys.

I note from another thread that there is a 3 spade relay under the dash? both that I've replaced are only 2 spade relays (Hazzard & Signal or so I thought), I feel I may of overlooked this 3 spade, Is this relevant to the indicators?

I'm just confused why everything else works but the indicators, nows the time I wish I was more mechanically minded and I probably could of figured this one out by now :D

Thanks
