My car has been at the dealer in Hobart for 4 months whith some type of current draw. Mitsubishi seem to have no idea how to fix. Please help!

place an amp meter in the circuit of the battery earth wire and get an idea of what the current draw is so you can have an idea of what piece of equipment is using the power. Radio amps require a big draw where glove box light, boot light, interior light are small draws. If it shows a medium draw the pull the ECM fuse, or IGN fuse or light control module fuse to see if the current draw drops . Even new alternators can be faulty especially if the unit was not wired up correctly and blew a diode. All it takes is a simple touch . have an accredited auto electrician check it out on the bench

remove the earth wire of the battery and place an amp meter in the circuit to get some idea of the current draw. Low current1-2 amps will indicate a light on ( glove box light---boot light) higher indicates a much bigger short possible through a relay coil or fuel pump

you need to go to a mitsubishi dealer they will give you the code for a few dollars or there are plenty of sites where you can get it for free, just type in free radio codes select a page type in your make and serial number of the radio and someone will come back with the code, i had a reply in ten minutes with the code i needed for mine

Hope this helps, let me know if you need more information

Thanks

Every week its a good idea to check tire and oil pressure, wiper fluid, coolant, the usual's. Oil changes every 3-5 months, and check-ups at least yearly with your dealer. If you bought it new, the dealer often supplies a maintenance package for the first few years.

Test charging sys.and test for current draw,may also be a tracking sys.

Change or recharge the battery. Repair any exposed wires (insulation broken or worn off) on wires in affected circuit that may be shorting out and drawing current from the battery.

Fish engine is suplying whith hydrauliks roker arms and is very sensitive to oil temperatupe and have big oil pressure in it

You need to have your electrical system checked for excessive draw. If the shop that worked on it has not done so, bring it to another shop...This is a routine procedure which definitely should have been done at least after the second battery! I can't offer a solution or "quick fix" because without doing that procedure I'd only be guessing!!!
