Probably on all cars, all years, all makes (with negative ground), the commonest answer is a bad ground connection, the one from the negative cable on the battery to chassis ground. When your car acts up, take a battery jumper cable, connect it from your negative battery terminal to the nearest part of the chassis you can reach (I use the alternator frame) see if that's your problem. If so, that ground connection should be at the right rear of your D. Or do it another way, with 13 plus volts across your battery terminals take a VOM and measure from the positive terminal to chassis ground and see if that reads 13 plus volts. There are some far out answers like the cables themselves, once in a great while a bad connection from the cable to the lead connector that actually connects to the battery but those are rare and can be immediately checked with a VOM also. You can also measure the resistance from the negative terminal to the chassis (again, I use the alternator frame) should read about an ohm and a half, if it's more than that be suspicious. Your battery has the proper voltage and you have a good starter, the voltage isn't getting to it. paulus260572 wrote: > Hello all, > > The problem I'm having on starting is this sometimes when I crank the > car over its like the battery is flat and there's hardly any reading > on the volt gauge then all of a sudden the car will start and be fine. >
