wiring / fuse panel set up

(1/3) > >>

grdra1:
I am about to attempt to wire up my altered, blown mechanical alcohol injected 392 hemi, supermag 4, onboard starter, 16 volt lithium battery, rpm data logger, powerglide, transbrake. I am after pics / advice on how to set up, I after a basic no fuss system. My knowledge is limited in this area so all info will be greatly appreciated. Thanks in advance. Glen

Basic would be just a kill wire for the magneto, a receiver for an outside plug in battery for the starter, small compact battery for the TB and logger

sorry for cutting in on your post!
 how many AMPS kill switch with a mag had a customers car that wouldn't shut off switch was bad i installed a 30 AMPS switch is that enough?

dreracecar:
Can vary depending on the magneto amperage, but for what we do you should stay away from auto parts store switches and find a Cole-Hersee distributor for a quality unit. Usually a boat shop will have a push-pull switch dipped in vinyl  that holds up well. Also you have to pull out to ground the mag so bumping it while the car is running wont ground the mag out which can happen with a toggle.
 All cars (injected or blown) running alc should be shut off by the fuel pump shut off valve until the engine quits running and then the mag kill switch as a secondary backup until the time the engine needs to be started again

My son dose a lot of wiring jobs on race cars and before he starts will write down every switch and what component they go to . Use a different color wire for everything helps . Terminal blocks help keep everything  nice and neat . Another helpful tool is a heat shrink label maker .
