Has anyone got a copy of the INTERNAL wiring diagram of the 40 AMP ISSPO gauge.
Heres the history. I have the shunt fitted between the battery and the master relay. This was an add in gauge as I already have a Volt meter and a low volt warning along with an alternator fail warning. Thus I put the shunt before the Master Relay and not after.
Heres the problem. The VANS gauge has 4 connections behind it. 2 inputs from the shunt - 1 X instrument power and 1 X Ground. (Plus a lamp - but these are seperate) Somehow I am getting a battery drain when the master is switched off. It appears to go via the shunt to the ground through the instrument ground. (Bypassing the M/S)
Does anyone have an internal for the gauge so I can confirm my troubleshooting? Does anyone have better ideas? Is my gauge working?
My thoughts are
Move the shunt after the solenoid.
Get a gauge that does not require instrument power and ground.
