Why does my CJ gauge not move from zero psi?
If the needle does not move from zero psi then, either the wiring (open circuit) or the gauge is bad. If it does move, the sender unit is bad. It is very common for the sending units used with the 258 and 232 engines to be inaccurate. Make sure you have a good connection to the sending unit.
What should the voltage be on a CJ gauge?
S to A 19-21 ohms A volt meter can be used to measure the voltage between the A terminal of the Temp gauge and ground. It should be pulsing and averaging about 5 volts. If it reads 12 volts the Jumper Strip/Regulator is bad. If it reads 0 volts, it has been burnt out.
What should the resistance of an ignition coil be?
Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal. If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one.
Where are the temperature terminals on a CJ gauge?
Temperature Gauge A Terminal – Jumper from fuel gauge A terminal (Jumper Strap regulated to 5v) Some manuals have the positions of these terminals incorrectly identified. You can see the letters stamped in the insulation material around the posts.
