Looks like the control box on my P3 Rover is playing up on tick over it shows about 10 to 11 volts but as soon as the revs go up it jumps up to 20+ volts and when it returns to tick over the volt meter sticks at 20+ volts for two to three seconds then drops down to 10 to 11 volts again, any one know of any way to adjust/clean or service these if not dose any one know of where one can get one it’s a Lucas 9 post 12v type RF95. Holden classic car sells one for £99 ex vat here’s the link

Any one know where else I might find one or if it can be repaired? Thanks for you help. Steve

Hi Steve,

It sounds as if your regulator contacts are stuck together.
Look up the Control Box (Section 5) here: http://tinyurl.com/yaho9gu

Thanks for the help chaps. I mentioned volt meter in the last post but I was working off the dash mounted ammeter but as I've not had a lot of time today after work to sort any thing out so I settled for cleaning the terminals with WD 40 and fine emery paper as some one on the Rover site suggested and it dose seem to have made it a bit better, on tick over it reads just under the zero and now when you rev the engine the ammeter rises and falls with the engine revs and only go’s up to the 20+ point on high revs it also doesn’t stick like it used to dropping as soon as the revs do, there is a chap I know who is an auto electrician who is going to go through the whole system for me but he cant do it until next week so I'll keep you posted when I get it back from him.
