Holy Crud!!! More Under the hood electrical issues... PLZ HELP!! PICS!!

id think it wouldnt cause low voltage, just wouldnt allow much current through the wire...

right?

If current is being restricted to the point that not enough can get through to charge the bats, the voltage will drop because the demand is greater than the current can give. Same concept if you're running a system too powerful for your alt.

true

instead of your amps pulling less current, the voltage will just drop

i got that, my bad......i dont know what i was thingking.

still on the same topic...but not the same issue..

So I was just thinking.. is there a way to tell the MOST amount of power you are running by the size of the inline Fuse... Im running a 200A fuse, and the amp is rated @3000W... If the battery is running at lets say 14.2V constant... by math, wouldn't that tell you what the most amount of power you can run before you blow that 200A fuse... mathematically?? anybody good with their math equations?
