Hi everyone,
This is my first post and I'm just hoping that there is an electrician amongst the members that may have a solution to my problem.
I have a Sprinter conversion with a Bonus PMS3 power Management system fitted. 99% of the time it works fine, but occasionally it refuses to supply 12 volt power. When I check the input from the battery it reads 12.65volts input on average, when I switch the unit on the input voltage drops to about 3volts. Strange!
If I leave it off for about 15 minutes and then retry it, it works. I have changed the unit on the warranty on the assumption that the unit was faulty but it looks like the fault is onboard the vehicle.
Any ideas would be helpful.
thanks
