Clive, I've got some more measurements for you. With the relay pushed in: G=0.1V M=0.1V Q=0V I high=18.1V I low= 0.52V X=25V Y=18V Z=24.8V J=24.8V K=24.9V I hope these can help you. My system is still working fine and the relay is clicking away. I've moved to another problem now. I took it out for a bit of green laning and it was a bit wet and my indicators have given up. More fault finding to be done. Also my heater fan is shorting out somewhere. Its already gone through 2, 35amp fuses. Its a good job I love the old girl. Jim

Clive, Sorry I've been away so long. Duty calls and all that. It looks like that resistor is a definate weak point. Your has well and truly gone. I've no idea about re winding it but a shorting wire definatly gives you a working system. I got some results for you but I've go to re-do them while pressing the relay closed. Ignition on, everthing connected: G=0.35V M=0.05V Q=0V X=0V Y=0V Z=0V J=0V I=0V and K=0V With the engine running and the system charging. G=0.4V M=0.2V Q=between 13V and 25V X=28V Y=20V Z=open line J=open line K=28V I=1V I definatly own you a beer or few for all the help you've given my. Thank you very much. I'll get back to you with the rest of the results, Jim

Clive, Problem solved. My dad and I took the resistor off and found that there was a break in the wire so we sorted the wire out and all is now good. I've got a steady 28volts getting to the batteries. All thats left now is to find the rest of the system to put it back as god intended. Thank you very much for all your help. You've helped me learn alot and I'm very greatful. How is your 'all charged up' part 4 coming on? I hope your having some plain sailing. Jim

clive, done it. I've got 28volts again. Your a star. I've put a bit of wire accross the resistor to short it out, the wire has about 0.3ohms of resistance. I take it will run like that. What can I do about fixing the problem? All my thanks, Jim

Sorry clive in my haste I miss read you. is the resistor connected only at one end, circled? Because if that is so I think my resistor must have failed.

Clive, Of cause you were right. There is no connection from point X to the board. Where is it ment to connect to and can i just solder a new bit of wire in from point x to either the board or the next resistor?

clive, your one hell of a man. I'll take the fiddle with the boards. I'm going to try and tackle it now i'll let you know what happens.

ps check for volts from U and V and neither had volts with the relay arm pressed.

Clive, I got no volts on any of the terminals you labled in the picture. The ignition was on and the relay arm was pressed and I checked with it not pressed. The generator was not connected, nor was the cable to the generator. Does this mean that the battery power in could on the wrong terminal no putting the volts where we need them?

I've just tried again and I got no volts on F at all and the same goes for V with and without the relay arm pressed in. i checked the earthing for the panel casing and it is good. I guess this gives us some clue as to what is going on. A new panel it maybe? Jim

Clive, I think we may have found some faults. With -ve pin on earth and +ve pin on F I read no volts. Then +ve pin on X and the relay arm pressed down it showed 24V. As the relay was released the voltage started slowly dropping. With +ve pin on V there were no volts shown. These readings would sugest that the generator panel is at fault wouldn't it? Is it possible to point the finger at a component and then replace it? Or shall I try and find another panel? I have attached a picture of where my earth wire is connected inside the panel to confirm it is in the right place. (indicated by the arrow).

I've got it on a bench but I can put it back in the vehicle. Where in the generator panel is the earth cannection? or the battery connection for that matter. I only have a really rough Idea where things were connected to. Could you do me a picture of the 'outputs' of the generator panel so I can make sure its wired up correctly. Lets hope we find something.

Clive, I got the results for the battery bulb test. +ve prod on W and -ve on the heatsinks and the bulb lights up. Reversed and it does not. -ve prod on X and -ve on the heatsinks and the bulb lights up. Reversed it does not. -ve prod on F +ve on the heatsinks and the buld lights up. Again reversed it does not. Not what I though was going to happen but that gives us proof that the diodes are doing something inside the generator. I'm still trying to get hold of an AVO to measure the resistance. On a light note how is your new project getting on, all charged up 4? Hope all is going well. Jim

That sounds rather painful! Are EMER's the military publications? If I know the military then everything is in the wrong place and repeated at least 4 times. Making sure its far to expensive. I'm sure putting heads together can make sense of the mess. But even so it sounds like your making good progress. I'm on the edge of my seat in anticipation, it should make great reading. I've been out working on other machines today and your right, playing with images in paint is much warmer. I have just got the feeling back in my right hand. The things we do for vehicles we love.
