Igniter experts- what are these loose wires?

[Brownd3max]

Hey all- my '77 40 has these wires hanging loose on the igniter. The 3rd male connector at the bottom is from a condenser which is tied to chassis ground. I figure (maybe) one of these hanging female connectors are for plugging into the condenser upon igniter failure (?) And the other one?

See if the second post in this thread will help.

Don't know the year of your ride but here is the wiring diagram for a '79 that has an ignitor. Clicking on the link will open a .PDF diagram.

The small black yellow wire is resistor bypass, not required unless you live in cold area. Increases voltage during cranking to 12+ volts.

Do you have a gear reduction starter?

Throw the whole thing away and get a pertronix. Best decision I ever made. All you will need is the coil.

Here is how my '77 coil & igniter was wired before I installed "Mr. T-hole's" electronic dizzy.

I think the condensor that goes to chassis ground may be a noise filter for the radio.

Just to confirm: the connector toward the right of pic is power from ignitor bypass terminal on starter. Hook it up if the starter solenoid has the extra terminal for it.
The remaining 2 wires are noise suppressor. Plug them together, if not for you, then for others nearby with radios.
The 77 is a good setup, it has adjustable vacuum advance, a better ignitor than 74-76, and an emergency backup ignition system in the form of ignition points & a condenser.

Thanks guys for your responses.

Curt- I believe this is the original factory starter- was a GR starter an option? And why wouldn't I (or anyone else) not hook up the resister bypass if available? Is it detrimental in any way to leave it hooked up? Thanks for any info!

I'm not Curt, but I play Curt on TV

The GR starter shows up in the mid 80's. It cranks faster and uses less amps, but lacks the extra ballast bypass terminal found on 73-78 starters. The stock 77 starter will be a big direct drive starter with a short pigtail coming off the solenoid to send power directly to the coil when cranking (aka ballast bypassing).

Ballast bypass is a good thing, hook it up if possible.

One can make a GR starter do ballast bypassing with a SPST relay and a few connectors. I drew the circuit up a couple of years ago using a small solid state 4 pin relay, but never built one as there seemed to be no demand. On paper it's a very simple circuit, but actual plug and play implementation is a bit more complicated. If someone actually needs one, send me a PM and I will take a more serious look at making this an available kit.
