My ex-Teddesley nb had problems of intermittent fuel solenoid (connections refitted), plus fanbelt failure leading to flat battery and subsequent jump-start.Following all this the oil presure, eng temp and voltmeter have failed to register although the warning lights seem ok,and rev counter showing but low. Engine starts and appears to be charging ok. Any chance you can suggest where I look? I've limited elec knowledge and otherwise will call in electrician. Many thanks, David

I would be looking for a wire that has fallen off. Try behind the ignition switch on the terminal that comes on with the ignition. I suspect there will be two wires there, one for the charge warning lamp and the other to feed the instrument. The instrument one may have fallen off and it may also have a fuse or circuit breaker in line. Also check the instrument panel negatives connections right back to the battery negative. I wonder if the jump starting has knocked a connection off the batteries. Before I would comment on the rev counter I would want to know the charging voltage after several hours running. but check the small W (rev counter) terminal on the back of the alternator for security.
