[DeTomaso] NPT Diagnosing turn signal failure

[Doug Braun]

Ken,

I have two suggestions for questionable fuse contacts.

1)  Buy a can of De-Oxit and spray clean them.

2) If the De-Oxit doesn't cure it, buy a bottle of KopR-Shield and spread some of it on both fuze blades.
Be careful, it's messy but very effective at improving and sealing an electrical connection.

 Thanks Thomas,
Good Point, I assume the flasher relay has to be before the switch to operate the right and left turn signals.
I replaced the flasher relay, still doesn't work.  Before diving into the multi-function switch I checked the fuse which was good, put the fuse back in, and now everything works???
This may have happened before because I had this problem a few months ago, had checked the fuse, and then the next time I drive the turn signals worked.  

Can a slight amount of corrosion on the turn signal fuse add enough resistance to keep the flasher relay from working?

 Normally the relay sits before the switch, so you will see +12V there whenever the ignition is on. You can bridge from that pin to the relay output pin and operate the switch. That should turn the lights on solid in either direction. If that works then it probably is the relay that is faulty.
