Inertia to pre-engaged starter wiring trouble
Turbo Mini Forums

Keeping it simple I’ve found out I’ve got an early loom (the one with the junction box and inertia starter)
And trying to get my A+ pre engaged engine going!

Now if I had the junction box I have found A way to convert it and use it as a sort of relay
But I’d have to buy a new 4 terminal starter solenoid for that and am wondering if there’s an easier way?
Or should I just suck up and order one?

Also I’m not sure if it’s related but while hooking up the big brown terminals to the constant live I wasn’t getting any power to the fuse box, headlights or ignition?

Been working long hours at work lately so not sure if it’s that that’s made my brain abit fuzzy and pretty frustrating only getting a few hours a week to work on it!
Thanks

What are people doing there? Reducers?

Don’t remember having an issue on the older setup! Haha

You definitely need to use some sort of relay to operate the pre-engaged starter solenoid or your ignition switch barrel will fail (maybe not today, maybe not tomorrow, but it definitely will....)
Using the inertia wing mounted solenoid is the easy solution (although far from the neatest) so you just have to mess around with the big cables to use it and whether it's the three or four terminal version just depends on whether you have ballast coil ignition or not but all the pre-engaged starter solenoids I've seen have had the extra connector to bypass the ballast wire anyway. That's not to say all do, but the ones I've seen do. In which case you only need the three terminal wing solenoid to act as the relay.

Like this?



It's not pretty, but worked for many, many years without any trouble...

Not the usual solution but, in conjunction with the wing mounted solenoid, it would certainly work. (without the wing mounted one as well, the starter would just run all the time).

Personally I just added a new standard 30A relay relay like the later cars had but i was adding lots of relays anyway for the EFI so another one for the starter was no big deal.

Ok I’m running mappable ignition so coil isn’t an issue really

Now I’m wondering why when I hook up the brown ring terminal to 12v why i’m Not getting power to the loom/ ignition :S
