fuse blows when cranking over
Wednesday, October 14, 2009 10:23 AM
So i relocated my battery 4 months ago in to the trunk.im running 4ga wire all the way to the stater with a now 100 amp fuse about 2 feet from the starter.Lately iv been blowing a couple 80 amp fuses so I went out and bought 100 amp fuses.this week iv been thru 4 fuses. Its been getting annoying to change this fuse every other start so any help will work.Also they are the glass type of fuse that keep blowing. Hopefully by the end of the week ill be able to get the anl? type fuse holder and fuse.

Starter amperage draw is high. Try 120 or a 150 amp fuse.




Your car may do 13 sec @ 103 mph, but my car does 146db @ 35 hz.

200 amp circuit breaker on a stock alternator is not effective. The wire would melt before the breaker trips. 150 amp is what 4 gauge is rated for.
