Too many amps (question fo you electrical people).

**Telos** · 11-21-2004, 10:57 AM

I've had my car computer running for over a year then one morning, completely randomly the inverter goes into protection mode and won't supply power to my computer. I checked the voltage between the terminals and found it to be about 12.15 volts. I was unable to check the amps running through the cables but it is definitely too high because the inverter goes into protection mode. I've also tried a different inverter with the same outcome. I've tried switching the grounding position with no luck. I'm completely stumped. I just have no idea why it would randomly do this. Any of you electrical wizzes know what the problem might be?

Thanks.

have you checked the fuse on the inverter?

One possible cause is that your computer's power supply might be shot. Try your inverter on a different power supply and see if it works.

Have you tried turning on the inverter without a load. As xtm said, it could be your PSU.

whats the voltage coming from your alt? alt might be dying maybe battery. when voltage drops amps increase causing heat and fuses to blow.

This happens with or without a load on the inverter. The fuse on the inverter is fine as it powers up and is running but will not supply any power to anything. As stated before there is a voltafe of 12.15 volts from the battery, which is only 2 weeks old. I'm really stumped on this one. Anyone else have an idea?

IMHO, there are only a few possibilities:
1. the inverter is simply bad.
2. there are loose connections to the inverter (check all power wire connections, both sides of the wires and positive and negative wires), which would severly limit the current to the inverter, causing the low voltage alarm to come on
3. The fuse Looks fine, but in reality is damaged. People with OPUS power supplies have experienced this occasionally. Try replacing it with a brand new one.
