Hey all,
Well, my 68 sprite seems to start ok for a few runs, then click...rurrr ruuurr. I can put a charger on the battery and she starts up again after a while. I started looking into the dynamo for a problem source. I searched on here and did some testing. I had the car running and it looks like 12V across the battery(although I kinda have a crappy multimeter and telling between 12 and 13 isn't that easy...but it's definately not 14+V) I also disconnect the wires to the dynamo (NY and NG, jumpered between the dynamo leads and read the multimeter between that and batter hot. It still looked like the same ~12V. I did all of these at idle and higher RPMs(not sure exactly what RPMs, my tach never goes above like 500 RPM for some reason). Still same ~12V all the time. I also have a 62 sprite that's on temporary or permanent hold, so I scavenged the dynamo from it(tach drive type..which I had already cleaned and painted years ago). I put in on, made sure it was magnetized correctly by removing the NG wire and jumping that terminal to hot on battery a few times. Started right up, but same results as for other dynamo. I also really don't know if either of the dynamos work. I've never had them tested or anything(if they can be). Inside of voltage regulator looks clean, outside spade terminals are a little dirty looking. Ignition light comes on when key is turned but not cranked. As soon as I crank/start engine, it goes out.
Also, not sure if it matters at all, but I have the crane XR-700 ignition.
Any help here would be appreciated?? Sorry for the long message, just wanted to get all the info in there.
Thanks - Drew
