issue caused by volt booster?

[Warbeaver]

So, the last several months, I have noticed that my Voltmeter gauge has been acting funny. The volt reading on it has been fine, it's just that the red light keeps going dim for a couple seconds, then getting brighter, then dimming, etc. I messed with wiring, ground, the bulb and still same problem. I also noticed that my driver side fog was flickering a tiny tiny bit. For some reason, i went to my alternator, and took off the zzp stage 1 volt booster.

Haven't seen the problem since last night.... so, could too high of volts cause this? or is it something defective in teh booster? i was pushing over 14.5 volts using it. without the booster im at 13.9-14.1

I run the stage 2 volt booster on mine and haven't experienced anything like what you have described.

yeah idk...only other thing i can think of ,is the battery. its newer, but the cold cranking amps were lower than my previous battery, (they were out of the right battery and it was a free replacement). I can't even remember how high our cold cranking amps should be?

its either that, or could it be the alternator?

Gm alternators always surge a little bit. Dont worry about it.

yeah, im just gonna watch it and see how it goes. its just weird that it quit doing the dimming and fog flickering after i took the booster out. I have heard about some defective ones doing some weird things...

something i just read on zzp's site:

"New version has better soldering. Fixes the erratic voltage issues on certain cars. Now compatible with Regal and other 3 wire applications!"

im wondering how long that has been for?

If there is not a proper connection or the 'signal' wire is not connected, the volts bounce around like you described. I would pull the booster
