Definitely seems like the regulator is malfunctioning - at idle it’s close to 17v and climbing. Thanks for the info here internal regulator in the alternator must be malfunctioning

I’ll recheck but I read that at idle it’s reading over 19 and about 2500 rpm’s it’s down to a normal range - it was a charging test. Internally regulated alternator

Been having battery issues - ran a charging test and my unloaded reading was 19.4 while my loaded was 12.4. What could be causing that? Faulty alternator or wiring? Seems odd to me that unloaded would be higher than loaded? Having a hard time diagnosing the issue

EXACTLY what I'm looking for! that's incredible, may just have to pull the trigger and ship it

Ha! Man if only!!!

Didn’t really know where to post this so I went with somewhere I know I’d get a response. Long story short… getting married in September in Atlanta and being an fj40 owner I was wondering if anyone knew of a place that had one for rent for the getaway vehicle. Looking for one with the top off -...

Mark can’t thank you enough, you nailed it! Pulled off the panel, bent the starting position for the needle to read L and now idle it’s in the middle of the gauge. Such a relief

Mey mark think you might be onto something here… can’t even see the needle on the gauge when the engine is off now…. Looking thru older pictures it appears to sit just below the L…… frustrating!

Were you able to find anything here?

I have the Haynes and it’s got the same instructions

gauge is maxed out when I do this so seems like it has to be an issue with the sensor itself or with it being grounded. Am I missing something with these sending units that don’t have the separate ground?? Was under the impression that they ground thru the threads. I even attached a separate...

Grounding the sender lead to see if the gauge responds? Will try tomorrow if weather permits and report back

Hey there — it’s a 77. Had the one without the ground (was told that grounds to the engine block thru the threads). Replaced that with the same one and now neither work, very odd. All signs point to a bad ground but having trouble testing that I’ve removed and replaced the old one several times...

Had an issue with my oil pressure sending unit — worked fine for a couple years then when I got the oil changed it would be pegged on the high side. Took a manual reading and it was writhing the normal ranges so naturally I replaced the sending unit. Now with the new unit I get no reading at...
