On the topic of saving the cluster, how damaging would a pulsing output from the alternator be to the cluster? I don't know the amplitude of the ripple, but I can see my dash pulsing at idle.

In my opinion, if you can see the pulsing, then the frequency will be way to low to cause any damage to the EL panel.
Ok good. I really didn't feel like swapping my alternator again right now.
well i know what im doing from now on! lol
I have that problem as well. I'm thinking there is something with my new kmj alternator. It does seem to log stable voltages at idle / wot but the gauges do pulsate a little at night time.
The issue is with the KMJ. The first one he sent me did it really bad. I sent that one back and he fixed it. Supposedly. This one does it as well. I have no interest in dealing with pulling it and sending it back again so I'm dealing with the pulsing for now.
Oh that's just great
. Thoughts on what you'll do to remedy the situation when you get around to it?
I have a spare hair pin style on the shelf waiting to go in. Then maybe replace the regulator and brushes in the KMJ.Oh that's just great. Thoughts on what you'll do to remedy the situation when you get around to it?
Just reading this thread, having been away from SVTP for a few years. Nice to see the solid analysis and shared knowledge here.
FWIW, my Speedhut "fix" is still working find, having been installed well over 10 yrs ago.

Thanks! Glad to hear that the Speedhut solution is still working after years. I was a little worried that the higher frequency might be bad for the panel, but your evidence suggests it isn't. The lower voltage may actually make te panels last even longer. Who knows. Good news though.
In my case (an 04 with ~80k miles), They started to fail intermittently. They would go out for a day or two, and then start working again. This went on for a few months, until they were 100% 'Tango Uniform'.
That was annoying, because I had no idea it was an "inverter issue". I swapped out headlight switches and played around with fuses trying to find the root cause issue. IIRC, this was in 07-08 timeframe, so there wasn't a lot of tribal knowledge and the dealers were just saying "buy a new cluster"..
