Has anyone installed a powerline starter motor to a Rover V8 engine in a P6?

I would think that the new starter doesn't have a terminal for an unballasted supply to the coil when cranking, only the main 12v supply to the post, and the switched supply to the terminal. If you have the ballasted system you should be able to get the 12v supply to the coil using a relay.
 
The trigger wire is the White one with the brown stripe, connect this to the spade on the new starter.

This will spin the starter when you turn your key.

The White wire with the yellow stripe goes to the coil to give it 12V when the starter is spinning to give you a better spark.
 
Thanks Richard. I thought I'd attempt this today.

White/brown wire into connector and battery cable to stud. I just left the white/yellow in place but taped the end off so it doesn't short out or so. Pulled choke out and turned car over and it started in seconds. (Would be quicker if I replaced my choke cable).

What a huge difference these starters make and sound like.

Alot easier to get the bolts in and I now know why the bottom mount hole is a slot. Also, it makes getting to the manifold bolt in the back corner easier.
 
Great news

If you feel the coil needs that boost during starting, I can work out how to get 12V to it, with a relay or something.

OK will do. Thanks again for the straightforward explanation. Electric stuff isn't my thing.
 
You can probably run a 12v supply to the coil when cranking by piggybacking a wire from the starter relay on the inner wing down to the coil. See which terminal on the relay powers up when you're cranking, and try that.
 
Car struggled to start this morning but when it got going it was fine. Went on a run and everything good.

Got back home and I thought I'd try it when fully warmed up. Struggled to start.

I think I made need this extra power from the coil. I can't check the relay as I'm on my own here with no help. What do we need to do to get that 12v from the coil?
 
The White/Brown wire is only live when the engine is cranking so you could just connect it to the White/Yellow wire to give 12V at the coil when cranking, BUT the normal coil feed will come back down the White/Yellow wire and may (probably will) keep the relay charged, and therefore the starter will stay engaged - not fun.

You can use a diode, which only allows current to pass in one direction i.e. to the coil, and not away from it.

Get one of these

...and plug the White/Brown into one end, then onto another of these spades, connect a wire to the terminal on the starter motor. So now your trigger wire is still going to the starter in the same way, but has a connector in it.

Then plug one of these into the other spade..

The other end of the diode (Male spade) should connect to your White/Yellow wire. The electricity only flows in the direction of the arrow.

I hope that makes sense.

Trying not to be blunt, but if you're really that bad at electrics, it may be a good idea to have a fire extinguisher handy, or someone who is good at electrics.

And don't use scotch blocks :)

I'd be intersted to know how you arrive at your username

Ha ha. I've never been asked this question.

amp are my initials. Alan etc...
whu are indeed what you say.

In regards to electrics, not my bag. I'm a heating engineer so the only electrics are a new pump, immersion or stat.

I can rebuild a car (look at my thread) but couldn't rewire the car!
 
For the record, since quattro gave out that useful info above, I've not had any starting issues. Even though I used the car after a 6 week lay up, I started easily. I still need to sort a couple of bits regarding tuning though.
 
I converted to electronic ignition years ago.
Better starting on the starter motor -within seconds, easier on the battery, smoother running , better spark plug life, better acceleration, better fuel economy. Bigger smile
I have a basic electronic ignition fitted to my P6, which does indeed work superbly. However, I do miss the vacuum ignition-advance with the points system. I don't know if there is an electronic ignition which can utilize the vacuum advance?

Forget lite weight starter motor !! esp if it aint broke.
I have tried the 'high-torque' starters before on the R-V8's. I've found that they're very good, reliable, dependable and refined. But, overall I prefer the original Lucas units nowadays; refined near-silent operation...very Rolls Roycey.

I spoke to a guy from Powerlite at Goodwood Revival this year. He says that they can offer rebuilt Lucas units now, in addition to the high-torque starters. He told me that the 3M100 units are the best quality, component-wise, and to steer clear of the 9M90 units fitted to later (80's) R-V8 engines.

hello i am in the same mess but "deeper" as my english is not that technical. My starter is out: it appears to me after test that solenoide contacts didn't do the job anymore so i tried to repear by melting out the spade welds, and removing solenoid cap, cleaning contacts then back and new welds.But problem was one stage further and in fact its the internal coil which is too weak: impossible for me to repare it.I am interseted now by this powerlite starter: iunderstand where the battery cable and the trigger wire go. but i dont understand where you connect this bl..dy white wire as i dont see anything on photos. Please could i have an answer as simple as possible to understand before ordering? Thanks for you help
 
Have a look at my drawing above.
thanks a lot but here is my limit: what do you mean by "coil" .:rolleyes: Thats bobine in French and the only one i know in inside the solenoid. On may it seems thad you had taped the white wire so related to nothing.
