M8Greyhound Posted September 18, 2005 Share Posted September 18, 2005 OK here goes guys....i need an electrical genius with a knowledge of 12v jeep electrics.... My MB has 12v electrical system on it....yes i know not for the purist but until i have the cash to return it to 6v it will be a "will do" for now. It has the Jolley Engineering (no point) ignition system on it and also a lucas 12v small regulator and 12v dynamo/ alternator ? I need to know if anyone has the same system how to wire up the charging system with the corresponding terminals and wiring please. On the regulator it has the terminals...A1-A-F-D-E so what goes where...i am speculating that F is Field and E is Earth and D is Dynamo......and that A and A1 are for charging lights etc. Also what wires come from the HT side of the coil and to where ? Any help helpful Thnaks in advance guys Regards Lloyd Quote Link to comment Share on other sites More sharing options...

Lloyd, If you have a Lucas voltage regulator, then you should have a dynamo and not an alternator. The terminal A on the regulator goes to the ammeter and from there to the live side of the starter switch. Terminal A1 feeds the ignition switch. Regarding wires from the HT side of coil.........there is only one, the thick one in the middle which goes to the middle of the dist. cap. :wink: Kewelde Quote Link to comment Share on other sites More sharing options...
M8Greyhound Posted September 18, 2005 Author Share Posted September 18, 2005 Top man thanks for that.......so if its wired up as per the MV spares complete new wiring loom....the under dash wiring will all be in place i.e charging system wiring to the 2 post Junction Block behind the air bath oil filter. The one that is confusing me is the single black wire with white tracing that says it comes from coil HT or LT ? side to distributor......as i have the Jolley Engineering ignition system do i do away with this wire as i already have pos and neg feed to the distributor. Also am i right in saying that F is Field,D is Dynamo and E is Earth ??? Thanks for the advice its musch appreciated Regards Lloyd Quote Link to comment Share on other sites More sharing options...

Wiring should be done using the correct colour codes for particular circuits and I see White with black tracer is "ign coil to distributor", that would be from the CB or + terminal on the coil. As I do not know how the Jolley system is wired, I cannot comment on that, assume it is already wired up from what you say. F, D and E is as you say, correct. regards, Kewelde Quote Link to comment Share on other sites More sharing options...
M8Greyhound Posted September 18, 2005 Author Share Posted September 18, 2005 Hi again Kewelde as you correctly say the Jolley system is wired correctly with red and black + and - wire taken from both terminals on the coil and that runs correctly as i have not changed that from when i started the restoration. All the other wiring is correct as per the MV spares loom and is correct to the 2 post junction block( charging circuit). All i need is the correct wiring directions for the dynamp and regulator. I know its as clear as mud isnt it ? regards and thanks for the help so far Lloyd Quote Link to comment Share on other sites More sharing options...
