Hello everyone I had a question about voltage. I am a newbie when it comes to wiring and electrical but I did my research and read the forums. I have a 1977 280z and it looks like someone’s been in there trying to figure out the issue. Missing bolts etc. anyways with my multimeter I tested the coil and the resistor and voltage. the voltage was off.. well there was none with the key on the on position, testing on the first terminal on the resistor. so this is what I checked, I went to the battery and checked the cables those are good, car turns over. I looked at the wiring d
Earlier today my 280Z started right up and idled just fine as it has done for the past 9 years. It was idling for about 5-10 minutes then it just dies. No stutter, no chugging, no nothing, just dies as if the spark randomly shut off. So I test my spark plugs, no spark. Inspect the distributor cap, looks good. Check the coil, no voltage signal from the coil to the cap. And that's my issue me thinks. So I pull the coil to test it. Primary circuit has 0.8 ohms resistance and the secondary has 22k ohms resistance. The values are a little out of range from what the book i have tells me, but
This morning i decided to swap the ignitor installed on my 240z and after opening the distributor cap i notice something is missing, i guess it could be the ground wire,so i fabricated one with 2 terminals and installed a new pertronix ignitor model 1761 together with a 40511 new 3.0 ohms ignition coil. The car cranked up fine, but whenever you step on the gas the tachometer does not read correctly. Once it reaches to 5,000 RPM it jumps to 7000 goes back to zero, etc. If you have the car parked and step on the pedal it raises to 5,000 goes back to zero. Bottom line it is not Reading as it us
