quote:Maybe voltage regulator overamping?
There is no such thing as "overamping", unless you have a short.
The Alternator can generate a higher VOLTAGE, but to burn stuff up, the circuit has to have a low-resistance path to ground.
As Joe stated, an increase in voltage might boost your current by 10-15%.
But this (relatively) small increase in current caused by the higher voltage will not be the difference between a fuse that doesn't blow, and one that blows in 5 seconds.
Electicity is like plumbing, were voltage is PRESSURE, and current is FLOW. Electricity always goes from the high pressure (voltage) side, down to ground (at least for the purposes of this discussion).
You need you get your multimeter out, and figure out how that FLOW on circuit XX (??) is getting to the drain (ground), by finding the wire or connection that has a very low, or no, resistance.
You have to figure it out by "boots on the ground", since there are a lot of wires, it is hard to help over the internet. Understanding how the electrical system really works will help you in your quest.
Good Luck - Seriously.
