Thats ok jeff but its steve lol..anyway jeff i have looked at the wiring on the alternator 3 wires red,grey,blue do i need to take all 3 out to find the charging light one?

Sorry Steve its my age lol.
Safest way to do it is one at a time, and check your battery charging light, if it fails to light when wire disconnected, Bingo you got the right one, if not reconnect and then try the next one, and so on.

Ok my Maplins split charge relay arrived today I still need to get some wire,connecters and an 8amp fuse to ncharge my 85amp hour battery. Looking at the diagram am I right in thinking that both batteries are earthed from the negative terminals likewise the unit is also earthed and that there is only one feed into the unit which is fused from the alternator? Think someone scanned a picture up of this unit somewhere. Unfortunately electronics is not my chosen occupation.

However you charge them, don't forget to check the electrolyte levels. My battery went flat on me today. When I took off the vent caps I could see the dry plates. We are not exactly short of DI water to put in them are we?
Made a note in my diary for the first of every month. CHECK BATTERY LEVELS. Dai
