    Need wiring for my race/streetcar....

    I can send a custom schematic as to how my truck is wired. We used all black wires with numbered circuits for the main harnesses. No AC or heater. Frame/chassis is custom CAD design chromemoly tubing. Single wire alternator but have wiring in place for standard alternator. PM if you think this...

    Tracked it down to the alternator not charging. Popping the dist/coil fuse do to low volts/increased amperage while cranking.

    Thanks 1 Wild R/T. Seems to start popping the fuses for the distributor/ coil circuit under mid to low battery voltage. When the battery is at full charge, the engine starts fine. I don't think the alternator is throwing enough juice to charge the battery. Drove it for about 5 miles tonight...

    Done troubleshooting for the night. Going to test the alternator (internal regulator, single wire) tomorrow. Also ran the engine in the dark. No blue flashes anywhere.

    Battery is behind the seat. Has a good body to engine ground.

    Intermittant Starting On Custom Build

    The fuse that keeps popping is a 15 anp in the coil/distributor circuit. Replaced the fuse, and the truck starts up fine. (until the next time it pops). I placed a rubber cap on each of the coil terminals thinking it's arching from the distributor wire to ground on the coil. Waiting on it to get...

    I don't think it's a bad relay. But I'll check.

    Intermittant Starting On Custom Build

    I checked for a ground from battery to engine. There is one there. Didn't see it right off until I lit things up. The ground runs from the cut-off switch to a bolt on the bellhousing. I would assume this set up would also ground the battery to the body.

    Thanks for the suggestions. guys. From looking around the battery, cab, engine, and chassis, there are no ground straps. Methinks this could be the cause. Sent the kid to O'Reilly's for a pack of five. Will report back if does or does not fix it.

    Intermittant Starting On Custom Build

    Hard to explain and possibly hard to diagnose. Please put your thinking caps on. The wiring on this build is totally custom. After a first time on the road shake out, things went well. Idle, temps, oil pressure good. Pulled in the driveway and parked. A few hours later, tried a restart, an...

I've been running this battery ( in a remote location), and it has performed flawlessly. XS Power Batteries D925 - XS Power AGM Batteries What's an added benefit...

    Ported vs manifold vacuum advance solved!!!

    Late to the party as usual. Vacuum advance is distributor diaphragm dependent/ designated. That's why there are debates all over the map on this issue. After all, it's the distributor that delivers the required advance. I run a pro billet distributor from 440 source. (ignition inclusive), and...

    That could possibly be a lead-in for an electric choke.

    Help - Trunk Battery Cable Routing

    Just a word of caution. I ran the cables for a rear mounted winch under the carpet to the rear hitch. After a couple years of people climbing in and out (stepping on the cable) the insulation wore thru. I had the wires switched at the firewall so they weren't constantly hot. Went to use the...
