Need Help....No Power

Wait, fusible link is cooked? -------just read that...


Sounds like a ground issue. The ammeter fluctuating is a sign that the charging circuit is modulating, ie changing due to a variable feedback loop, ie. voltage regulator signal. I would also check the ground of the VR, especially the electronic one as it uses the mounting plane as its ground. This wont help the no power in the cab issue, I think thats going to be the bulkhead connector. Remove it, clean it up as best as you can then pack it with dielectric grease (ask a cable TV installer for an old tube or use the tan axle grease) to prevent corrosion or a high resistance open. I had a Diamante that would just stop running randomly, it was the distributor harness that looked fine but had an internal open. I yanked on it and then it would not start..bingo!
