Do you have the schematic electronic diagram of portawattz 1000 dc to ac power inverter ?

I have had this same problem with several power inverters over time. The problem is usually one of three things.

Those starting with the simplest.

1. Too much current being drawn on the inverter.
Solution (Check appliances that are plugged in and make sure they are not drawing more than 1200 watts. If they are unplug the appliance that is using the most current and get an inverter that is more suited to your power needs.)

2. Some power inverters have fuses built on to them. Sometimes multiple fuses. Sometimes, one fuse may burn out leaving one intact. When this happens even small items draw too much current and over load the inverter.
Solution (Replace the fuses)

3. Improper installation. Inverters draw a lot of current. You must use the propper wire size for the inverter. I would recomend at least an eight guage wire directly fused and hooked directly to the battery. Of course like with all things the bigger the wire the better the flow of electricity.

If it is not one of those things stop into a truck stop electronics shop and have the person diagnose it.

Hope that helps.

Hi, remove the machines cover with the machine unplugged then look for disconencted plugs etc within the machine. careful where you place your bare hands.

If the inverter is blowing the fuse immediately upon plugging in the inverter (before you even plug something into the inverter) you most likely have a short in the 12V power cord. If you have an Ohm meter, you should be able to check the resistance across the two contacts on the 12V plug of the power cord. Wiggle it around some. If you get a very low reading, and especially if it's intermittent, you have a bad cord, which should be pretty easy and cheap to replace. My experience with these cords has been that their quality is pretty poor.
If that is the problem, maybe you can cannibalize a cord from an old CB radio, but here's a fairly heavy duty one on Amazon (they don't give an amp rating though) http://www.amazon.com/Truckspec-TSPSCBH-2CP-12-Volt-Platinum-Replacement/dp/B001JT5QF0

Testimonial: "Al, the idea on the Powerline appears to be the correct solution. The R was very low as you predicted. I'll change out the powercord. Thanks !"

I don't know if this will help. Have you looked for a battery on the circuit board that backs up the memory? A lot of synths use them and when they go the unit quits functioning. Some will start right up again once the battery is replaced others require a system update through a download. Anyways I always recommend contacting the company in question. They should be able to tell you simply whether it needs servicing or not:http://tcsupport.custhelp.com/cgi-bin/tcsupport.cfg/php/enduser/ask.php
