Well I'm on a roll for messing things up lately. Now I had my boost gauge wired to the green/white wire from the dimmer switch, but wasn't able to dim it, so I switched it to the black/yellow wire on the dimmer switch and the boost gauge now dims backwards of every other light in the car. When I dim, the boost gauge gets brighter and when I max out the lights the boost gauge goes dark. I flipped the bulb in the boost guage thinking it might be reversed polarity, but it did nothing. Any suggestions or ideas why this is? Thanks in advance,

Mike

 

what kind of gauge do you have?

 

I guess I should have metioned that...It's a Autometer Phantom mechanical boost gauge....sorry

Mike

 

well i have a Defi D



black end to frame for ground
white end spliced into dimmer wire for power




hope that helps some

 

The way yours is set up is the way I originally had mine, and it would illuminate, but not dim. That's why I tried the black/yellow wire. I'm not sure what the deal is, but thanks for the info.

I'm dealing with this same issue right now.

 

i had the same problem, gauge would dim in reverse of all other gauges. I just wired it to where it comes on w/ the lights now

 

Has any one actually solved this issue got the D gauge to dim appropriately??

 

Defi factory instructions tell you that you will not be able to dim this product. I would imagine it to be the same with any gauge. Why would you wanna dim your gauge anyway? Your gauge may not have a dimming circuit which would take the ability of read a signal from a potentiometer (i'm an Electrician). But there isn't anything "wrong" with the product, it just doesn't have the function your looking for .

 

I got stewart warner and i grounded the bulb to the black with yellow chaser wire on the dimmer switch and power it to the green with white chaser wire.Dont know if it will work on yours but did on mine.
