Hi guys thx for the replies.

Out there kicking this around again in the garage. Seems the highest I recall seeing on the voltmeter while driving was 14 plus volts.
With the battery resting, it's 11.7 volts this moment. When I start the fan manually I have seen 17 to 18.5 amps repeatedly on inrush or initial current but once running though it's 10-11 amps draw. So theoretically we could see 22.7 amps when using the 14 volts running How long would a 20 amp fuse last then?
11.7V/18.5A =14V/ xA
x=22.7 amps

Isn't the rule of thumb to oversize fuses for about 20% or 1/3 more than normal draw? So if it spikes to 18.5 amps with 11.7 volts what will we see at 14 volts driving?

As for tracing out the wire it looks ok. Nothing obviously damaged or compromised.

Last question.

Can a voltage regulator suffer if plugged in under power (with the engine running). I ask this because 2 weeks ago, I had low voltage on the gage and had a look under the hood ( lucky hunch) and sure enough the wheel alignment boys had bumped off the 4 pin plug to the regulator. I plugged it back in while running and it showed good charging to 14 plus volts. Could this have spiked it?? Its also the same weekend it managed to be left overnight with the battery hooked up at the dealership. Problems since??
