wiring
« on: March 13, 2008, 03:01:46 PM »
Ok i have a 76 chevy k10 and i just put a big cam and high rise intake and new 750 carb and msd ;D. i have had my truck running with these parts for about a week and the other day i went out to show my friend how it sounds. but right when i truned the key the motor was just about to kick over but it popped a lil air out the carb and shut off ??? i went to try to start it back up but there was nothing there. i thought i just blow a fuse but they were all good >:( then i thought it was something on the firewall but its all good ??? could it be my fuse box

So nothing changed over that time period?  Sounds like your timing is off.

Check your wires that come up around the back of the engine and make sure none of them grounded to the engine. It definitely sounds like you opened a fusible link..

Too much current flowing through a wire will cause the circuit to overheat. Your fusible link is the weakest link therefore protecting the rest of the circuit. Again if a wire shorted to ground and you have 800Amps flowing through a circuit with no load to ground it's not gonna take long for a 30A fusible link to melt. Start looking at the wires that come off of the junction block on the firewall and the wires coming off of your starter solenoid. Follow them and see if any of them are chafed or cut. Grab hold of the fusible links and tug on them to see if they stretch or break.
