ttyR2 Posted July 26, 2022 Report Share Posted July 26, 2022 I posted elsewhere that the fuel/temp gauges in my 521 are flaky and was told that I can clean the voltage regulator on the back of the gauge panel. I also found an older post where someone made a solid-state regulator but all of the picture links were broken. Would a 12V DC -to- 8VDC 1A drop-down regulator do the job? Or do the gauges need more current than that? I found this...looks like a trivial build, and I'd include a small heatsink on the regulator IC. https://www.circuits-diy.com/12v-to-8v-converter-using-lm7808-ic/ Quote Link to comment
datzenmike Posted July 26, 2022 Report Share Posted July 26, 2022 Yes, it looks like that would work. I guess build it to find out. Look up a circuit for 8v regulated using a zener diode? Quote Link to comment
mainer311 Posted July 26, 2022 Report Share Posted July 26, 2022 Just buy one on ebay, unless of course, you're looking for something to do. https://www.ebay.com/itm/203911962364?hash=item2f7a199efc:g:68kAAOSwl2NiVhXd Quote Link to comment

mainer311 Posted July 27, 2022 Report Share Posted July 27, 2022 C’mon, the one I posted is located in Illinois. And before that, it was from our friends across the globe. Quote Link to comment
