DLIDFIS I think good questions?????
 
OK, Im planning my set up and I looked at the wiring diagram I see this little BW black and white wire running power to every little thing in the engine compartment.

1. I was thinking wouldn't it be better to run say a 30 amp relay from the battery to the coils and the two leading igniters?

2. How would I wire the condesor into this little wiring mess? On the switch wire to the relay or after the relay?

3. If I ran all coils and the leading igniters off the relay would it be ok to run the trailing igniter off the BW wire?

4. Anyone have a bad igniter I can have for shipping only hate to gut a good one? PM please on #4..

Thanks,
Sean

I'm doing pretty much what you've described on a rotary powered B2000 right now. Both ignitors were dead so I gutted them both. Leading was dead for a long time, and Trailing was running both coils with the dizzy cranked far enough to line it up to the Leading mark on the pulley. When it died, the whole truck was dead in the water (road). The wiring was also sub-par and suffered low voltage throughout due to the fuel pump and an electric fan sucking from the same feed.

1. A relay is what I'm using on the fan and another relay for all three ignitors and coils. The fuel pump is the only thing sucking power from the key switch wire now.

2. After the relay. It likes as much voltage as the rest of the components (although it doesn't draw any milliamps to speak of).

3. You could do it that way, but why not run all three? It's better to have a hotter spark even though trailing doesn't really do much for power. I bet it wouldn't diminish the amount of available amps to the Leading ignitors or all three coils.

4. Don't gut a good one. Do what I did and file down a couple male quick disconnects untill they're narrow enough to fit snugly in the pickup connector.

Or somebody may send you a dead one. I gutted the only two dead ones I had. Sorry, but they have to go back on the dizzy.

Good luck.

why do you wanna gut it. its easier just to find another dizzy and cut off the wires to the magnetic pickups. it makes it easier to install/replace. yes, i have wasted several in the junk yard but thats just how it goes here.

It's a bad idea to cut the wires/connectors off the magnetic pickups for so many reasons. :)

I made my connectors to the pick ups with small male spade connectors then covered them with epoxy putty for a 2 prong connector works like a champ.

Thanks Jeff20b

one more. I read in the other write up that the aluminum plate would get hot to the touch, but was cooler then the area around the distributer. Do you think it would be a good idea to pull all the ignitors off the distributer and have them on an aluminum plate. I think it would also make wiring a little less painless have the components in one place. Just route the signal wires from the distributer, less chance for interference with less wires running next to them.

Here are some pics of my install if you're interested. I haven't wired the relay up yet, but otherwise it should help you out. I just got some male disconnects for the magnetic trigger and taped them together so they wouldn't fall out.

You could pull all of them off, or just leave the trailing one on. It's up to you.

Nice pics and nice job, Moses.

If the weather is nice tomorrow, I'll get to wire up the ignitors and fire it up. I can hardly wait! :)
