Fuel Guage and horns

[BDK]

Couple of quick questions on electrical. Anyone know how to quickly test the horns for functionality? Mine are not working but not sure of where the issue is. Fuel gauge is not working either (was and then stopped). Just connector issue??

Thanks

It should be easy... For the horns: first look for clean contacts on both points. First is the horn mounting to the body (ground) and second the positive contact on the back of the horn. When it's good then get two lines from the battery, one to the ground connection from negative and one to the positive connector on the horn from the positive pole of the battery. In the moment you connect it there it should honk. Attention: do not scare, it is loud

If they do not honk there is a small screw on the horns which adjusts them. It could be possible that by full contact and not honking you can adjust them by turning the screw. This is how I did it with some used ones from Don and the honk perfect ::thumb::

With the fuel gauge it is a bit more complicated - that could be a lot of bad connections - mostly in the instrument cluster and its voltage regulator there you have to test. All other instruments are working fine? But it could also be a bad connector on the sending unit - there are many posibilities and you have to simply test them all step by step. Could be also a hole in the sending unit float tank (the brass one) and it filled itself with gas which would then always indicate an empty tank. Or the gauge itself - it could all easily tested with some ground and battery positive connections.

Here is a good article about it:

Hope that helps!

Thanks Tim! checked the horns tonight and they are both dead sooooo need to give Don at OMS a shout and see if he has both available. Will be digging into the rest of the issues once back from vacation....

Much thanks....
