My car was fitted with an Edge Starter Burtons before i bought it.
The original Solenoid has been retained. Does that mean when starting the Ignition Supplies the original Solenoid and also the built in Solenoid on the Edge Starter.
Surely if the original Solenoid was removed and Ignition feed straight to built in solenoid on Starter this would use less power. Or am i missing something here!!
Thanks for your advice and help

The solenoid feeds the starter with its 12v feed but also a 12v feed to the coil bypassing the ballast resistor. You can't just remove the selanoid or the car won't start as it will have no 12v feed to the coil while crankingYou also can't just wire a 12v direct to the coil as the dedicated coil feed will feed back to the starter Motor and keep it engaged while the engine is running unless it has a separated return feed that is only live while the starter is turning. Not sure I have explained that to well but hope you get the idea.

Well I know exactly what you mean! Of course the Edge starter may have a 12v feed for 'start' ignition, it all depends on how it's wired as to what the system is doing. However, if it works I would suggest leaving it alone.

I think the original Solenoid fitted to the bulkhead could draw 10Amps which is a waste.
Two Solenoids!!!! for one Starter motor!!
I will remove the link wire on the Edge Starter and connect the feed White Red Tracer that was on the old original Solenoid.
Then put the heavy cables on original Solenoid on the same terminal.
That way i save 10Amps in the starting circuit and will help hot starting

Do you have a ballast coil? If you do then the car will struggle to start as you should have another cable coming from the original solenoid to the + side of the coil.

Hi Chris,
The car had a Ballast fitted which has been removed and wires connected together. A 12V Bosche Coil has been fitted.
On the Solenoid fitted to the bulkhead there is only one spade connection for the White with Red tracer wire from the Ignition Switch.

thanks
Alan

If your not using a ballast then you don't need to have any other cables running from the solenoid to the coil. Just make sure you have a full 12v at the coil while cranking and all should be good

You sure about that?

The white ignition live feed to the coil/ballast is still live when cranking, obviously if you remove the cold start and have a normal starter and ballasted system then it might not start due to the voltage drop, but a cold start wire isn't the only power to coil when cranking.



Sounds like you've got it sussed out anyway Alan.

An update, i have removed the short link on Edge Starter.
I have made a link wire White red tracer to connect to the White red tracer that was connected to the original Solenoid. This now feeds the Edge Starter direct. The big battery cables are now all connected together on the large terminal on the original Solenoid.
It took about 10 minutes to do and now the Ignition is only supplying the integrated Solenoid on the Edge Starter which to me is logic.

The problem is that the starter solenoid pull-in could take anything from 10 to 20 AMPS (this is a guess, starters differ), once the solenoid has pulled in the hold-in coil comes into play and that reduces the current draw cosiderably. All the starter solenoid current draw goes through a small set of contacts in the ignition switch or start button and they do eventually degrade and cause problems
Fitting a starter relay in series with the starter solenoid wire will save problems in the future
You could fit and wire a relay where the solenoid you have by-passed is mounted and use one of the following bobbins to join all the positives together

Many thanks,
I have a spare bobbin and i have planned to fit a Relay. Your idea will make a neat installation.

Relay fitted as on later 3000M wiring diagram + it is a fused relay 30A fuse. Just above starter so short cable run

Proper job
