Distributor, Ignition Coil and Electric Choke wiring question

I guess lots of folks have this problem...Pertronix has a Relay for this exact issue.

Arrives on Wednesday.... will save from having to tap into ignition wire from under the dash.

I trigger the Painless Wiring fuse panel relay with coil feed, fuse panel then powers ign, electric fan etc...

 

That looks nice. Thanks for all the help guys

 

Krazy Comet, that is pretty!!!!!!!!!

 

You need a full 12 volts for the pertronix, I run my coil and electric choke off relays one for each used original coil wire to trigger the relay and getting power directly off the battery. like Tom said only feed one thing per relay but you need at least a 30 amp relay for coil choke could be less but why, ground the choke to carb itself, you may be missing the 12 volt crank only wire to coil, also I see the pos coil wire running to the dr side, the length of resistor wire is dependent on the total length of wire from ign to coil, if you add another 2 feet will drop your voltage even more,as I understand, even so the pertronix needs 12 volts and no less,

 

Learning things the hard way here. Hooked up the pertronix relay... 11.3 volts to coil? Dumbfounded. Multimeter shows 12 going in, nothing else hooked to coil. Test the ground of coil off the battery, 12 volts. Test the positive off coil, 11.3.

Not sure what my next step is. Try a new relay and coil?

 

you installed a relay for the coil and have 12 volts in to relay and 12 out but 11.3 off pos side of coil is that correct

 

Correct

 

Issue was distributor... now I get to wait.

 

dont know for sure but with the hot wire connected to the coil with the ign on there may be a small voltage drop at that point. the pertronix coil will operate from 10.5 t0 16 volts if I remember correctly but not 6 to 9 like stock point coil
