Mitsubishi Galant GS
2003
49,350
2.4l 4 cyl
Hi,
I am having a frustrating time with my Galant. The battery simply will not hold a charge. Jump started it last night at my friends house and he ran a voltmeter across the battery and it showed just over 14 volts, so presuming that the alternator is fine. When I switch off the engine however the power just drains out of the battery, and if I try to start it 30 secs after switching it off then it just clicks. My friend (who is a bit more knowledgable than I) was guessing that either it is a bad diode somewhere or something is shorting out and causing the battery to drain almost instantly. Do either of these sound plausible and if so, how can I check to narrow down the problem? Any other thoughts as to what the culprit might be?
Thanks in advance
