Actually the header is aluminum and part of the cab, not bolted or riveted.


Then you might get a fairly good ground right there. Bolt the bracket right to
the aluminum and run the black power lead to one of the bracket bolts, cutting
the wire as short as possible (no longer than six inches should be fine).


After working with it today I feel the alternator is the primary problem.
Since I have no ignition and no whine with the key in the ON position (Fuel
Pump), the alternator seems to be the culprit. I have been reading about
installing a micro_farad capacitor between the alternator and ground in
order to steady the voltage thus reducing the whine. I understand the theory
but could use some feedback about the practical application.

I feel this might be my least time consuming and least expensive solution.


You could try that, too. Find yourself a 'motor run' (NOT a 'motor start')
capacitor of around 1 to 5 uF. They usually have tabs for terminals so you can
use crimp connectors, and they can be mounted just about anywhere with a cable
clamp. Mount it as close as possible to the alternator, or even right on the
alternator if possible. Run one wire to the output and the other to ground,
again keeping the wires as short as possible. The capacitor is not polarized so
it doesn't matter which terminal goes to ground.

But know that some regulators are messed up by putting a cap across the
alternator. If you screw up your engine, don't blame me.
