Voltage Limiter upgrade

[John69RR]

Has anyone done this upgrade yet? I read about it in the Reference section.

I didn't do it but RPM sells a solid state plug in unit which I'm sure is the same thing for $70. I'm sure you can do it for much less if you have time to build one.

 

[John69RR]

Yeah, I've seen them now for $35.00 from one of the decal places. Someone had them for $50.00 now the price is coming down.

Yes I replaced the old regulator with a 7805 with a heatsink. One thing they don't mention is, that when a 7805 goes, it usually shorts out. That will fry your gauges. Good insurance is to add a 2 amp inline fuse on the output of the 7805. Or as said, buy the pre-made ones as they are output protected...

This guy has them for $50 on Ebay

Thats reason enough for me to buy the solid state replacement. Thanks.

From the looks of the ad picture it looks to be a plug in piece. Is that the case? I couldn't find any info on changing one out in the reference books. And if it is a plug in, could it be done without pulling the gauge cluster out of the car? This seems like a good thing to change out.

You should be able to reach up behind the dash and pull the old one out and plug the new one in. I would disconnect the battery first though.

Thanks John, and yeah, disconnecting the battery would be a given!

I was polishing up the lens with some tooth paste and noticed this topic

While it is apart and easy to do is this another thing I guess I need?

What about the condenser looking thing attached to this? Can that stay or does it have to go?

 

[John69RR]

That condensor is for radio frequency interference. The instructions that came with the solid state limiter say it CAN be used with the capacitor. Here is a link to the RTE site.
