Generator light at idle, regulator buzzing

finishing restoration, added console gauges, new firewall forward harness for gauges, conversion harness for console, charging system works fine (but), generator
light below 1200 rpms., and regulator buzzes, grounded regulator, no change. Charging voltage is good. Anybody see this problem, anybody run into this? Thanks, Mark

Re: generator light at idle, regulator buzzing

The regulator buzzes? I'm pretty sure the buzzer is in the horn relay... Anyway, maybe the connection for the buzzer on the driver door is messed up? It is the same switch as the dome light, but has it's own wire (two wires to switch). Or the ignition switch?

I wonder how the GEN light is now connected? Is it in the same circuit as the gauge? If so, it is probably acting like a gauge - below a certain voltage, it lights up. I think it was either zero volts or...10V or better that made it go off/on? The '67-8 cars that came with gauges didn't have the GEN or OIL lights... They just have BRAKE and FUEL lights.

How does the conversion harness work? Does a harness run out the firewall? Do you remove wires from the instrument connector? I wonder if one can combine Front Light and Engine harnesses that are for gauges and the conversion harness? Though, the only changes are the temp connector type and removing the oil sensor wire... Oh, and the tach wire.

I guess my first question should have been what year car you have... I'd have to break out the '69 AIM (and hope it's accurate) to help w/ that!

Re: generator light at idle, regulator buzzing

It's a '69 and in the instructions on the conversion harness they didn't tell me to disconnect the generator light. Complete new engine harness for gauges, some conversion harness wires just plugged into the fuse box, none went outside the firewall - disconnect some wires (gas gauge, etc.) from the instrument connector but not the generator light. Ithink the generator light still has to be in system for charging system to work, but not sure. Amp gauge just senses voltage between 2 points. Thanks for any help.

Re: Generator light at idle, regulator buzzing

After dancing for several weeks with my original style regulator I went to internal regulator alternator. In your case I would replace that OEM style regulator with a electronic one and see if that changes it.

Re: Generator light at idle, regulator buzzing

when I rechecked the voltage it would turn the light on when the voltage went up past 16 volts & start buzzing. Actually I bought an expensive Ecklin new one and it was defective, put on a cheaper one, all is fine, thanks for the help

Cool!

Wow, 16V. That's crazy!
