Key on 12v

[notlimah]

Hey guys, finally getting around to wiring up my trans gauge. It's the isspro ev gauge so it comes with the amplifier box. I'm already using a couple other key on 12v sources so looking to use another one if I can. Is there a list or diagram I can reference to check? 

 

I tried splicing into one one in already using but I'm not getting correct reading on th gauge so I'm trying to isolate the power to help troubleshooting.

Could it possibly be not getting enough current?  If you have multiple additional connections you could try setting up a switched buss bar that is controlled by a relay.  That would give you plenty of current for multiple switched add on items.

 

Just a thought

Yea that's what I was thinking which is why I'm trying to find another source. I'm wondering if just hooking it to a constant 12v to check and see if it's working is what I'll need to do to verify.

That would work.

Well basically ran through all the diagnostic stuff on ISSPROs site and it seems like it's the amplifier that's bad, but I'll have to talk to ISSPRO and see what they say.
