Voltage Limiter / Gas Gauge
« on: August 14, 2016 - 07:56:36 PM »
Hey guys, still trying to track down the gas gauge issue. Ordered a replacement gauge from classic, an still having issues.

Does anyone know what the voltage should be coming out of the voltage limiter ? It keeps fluctuating but the closest  consistent reading I get is  54.3 .  It will dip to 43.6 and as high as 65.0 but only for a second and drops back.  At present the temp. gauge doesn't work but I had to change the end that goes on the sender so that may be to blame.

5 volts pulsed .  Are you sure you on the right scale , those numbers seem x 10


Here's a good vid I found explaining it

A stock limiter pulses between 0vdc and 12vdc to give an average of 5vdc. The numbers you put down don't make a lot of sense to me.

I'll check out that video.

 I did a recheck with the meter down one click and got..   077 on the sender unit.  078 on the end that goes on the gas gauge  and 053 on the voltage limiter.

 Yeah watch that video ,  watch were and how he gets his 12vdc source on the limiter ,  get your meter settings right (showing 12-14 Vdc)  and then recheck limiter output and sender , cause those numbers are not normal ..

Best guess at what those numbers mean would they be mV? Just a small floating voltage due to a limiter that is faulted open?

 :iagree: What range is your volt meter set to?
