4.6 Starter Motor
Hi,
I thinking about fitting a Range Rover P38 starter motor to my 4.6 that i have in my TR7, at the moment it has a tired SD1 starter motor in it.
My question is, i have two connectors on the solenoid on the SD1 motor, one to switch the solenoid the other to by pass the ballast wire for starting.
Does the Range Rover have two wires on it
If not, any suggestion how to get round this
Cheers John

Re: 4.6 Starter Motor
Which SDI ignition system? Didn't think any V8 had a ballast resistor. The P6 did, though.john 215 wrote:Hi,

could you run a wire through a diode from the starter relay to the positive side of the coil? so when starter is switched on to crank the wire would become live to byepass the ballast direct to the coil... but once running the diode would stop current going back to the starter ?if you know what i meen??
The solenoid probably isn't specific to any one model, so the extra contacts are there for those that need it. Same as a rev counter output on some alternators - only needed with diesels.john 215 wrote:Hi,
Thanks for the reply's, the engine is in a TR7,which runs a ballast wire system. I am running a Mallory ignition on mine, twin point with a electronic pick up conversion.
Be intresting to know why some run a extra terminal and some dont

You could use a standard relay instead of a diode.
Connect the relay to the starter terminal on the ign switch so that the relay switches on when starter is running and then put 12v through the relay contacts to the coil +ve terminal.
Most motor factor shops have standard relays for a few quid.

If you already have a starter relay and it's just a SPST, change it for a twin output type.DEVONMAN wrote:You could use a standard relay instead of a diode.
