View Full Version : Vroooooooooom!

BCF... we have vrooom on my COPs/Megasquirt set up!

And what a long, strange trip it's been.

Lessons learned:

1) Wiring is hard.
2) Wiring is dangerous.
3) Never wrap it in tape until you have tested it.
4) Never work on projects involving electricity and volatile chemicals when wild fire danger is at it's highest level in recorded history.

Still to do:

1) More wiring
2) Research—I cooked one of my coils. I have not seen a ballast in any of the wiring diagrams I have looked at, but as the total resistance for all four coils is 2.2, methinks some ballast may be in order.
3) More wiring

This project has been keeping my up late and away from my family for a while now. I think it's time for a break.

Also, I am little drunk and I kinda feel like crying.

I love you guys!

Modern ignition systems control current flow to the coil electronically which negates the need for a ballast resistor. They have been since the introduction of the GM HEI, which is why I like to use the HEI module (even with my Ford distributors). If your coil drivers limit current you won't need to use a ballast. I am unfamiliar with your system, perhaps you may be able to research this aspect of it.

Woohoo! :cheers:

Though with no pictures or video, it never happened.

I like the part about being drunk and crying. Sounds like a typical combination for working on an LBC.

Lesson learned #5—If you drive a sheet metal screw through a bundle of wires, it is likely to cause a short. :rolleyes:

Anyway... vroom again today. The car fires up instantly, but runs disappointingly rough. :frown:

So more work to do.

#5a. if you drill through a bunch of house wiring while trying to install something like a new front door bell your weekends will be booked solid for a while or you will have to pay an electrician to come out and do a lot of work...
(don't even ask how I know)

Yeah, one of the fun things about putting nails and drills into walls is that you're playing Russian roulette with the wiring. Same probably goes for cars, as those wiring harnesses can be hidden in strange places.

As a nineteen year old "yout" doing the first MGB rebuild, I put a drillbit and a pop-rivet thru the rear harness when doing a floorpan repair. Didn't know it 'til it was time to check taillight function days/weeks after. That led to a fair bit of head scratchin' and consternation. When found hours later, it was highly embarrassing.

Me Ol' Fella thought it hilarious. I, not so much at the time. :wall:
