Battery Recharging - not!
« on: 14 March 2009, 12:14:53 »

This is going to sound like elementals but I have a dilemma, actually it's an Omega Estate. My car had been standing for about a month whilst I was using the company motor to get to and from work. When I came to use my "Hearse", the battery was flat. Fortunately, I had a a fairly decent journey home (and a battery charger as well), and so I jump started the thing and drove home. On arriving there I switched off the engine, and then tried to restart - Nothing, the interior lights dimmed and the multifunction display lost even more of it's pixels!
First conclusion was that it was the Battery which was terminal (Battery terminal?) Fortunately, a collegue was shortly going to scrap his Omega, and said that I could have his battery. I swapped my bad one for his good one, and was away -for about four days, then - dead!

Again I jump started the thing and drove it home. Again when I got home I turned off the engine and then tried to restart it - again, Nothing!

The questions are:
1/ If the Alternater was not recharging the Battery, why was it able to power the engine following a jump start?
2/ Would it be possible that the battery was discharging itself via some faulty wiring somewhere?
3/ There was a blown 30amp blade fuse in the Relay Box. Would this have anything to do with the recharge circuit.
4/ Does anybody know what that 30amp fuse is protecting? (Everything seems to be working without it!)
5/ Realistically what is my problem likely to be? I don't want to have to buy another battery if that isn't the problem.

Best thing to do first which wont cot you anything is to jump start the car and take areading of the battery with nthing on then put everything on. If the voltage drops to low like below 12.5 volts with everything on then the alternator is at fault. If not then you have a fault somewhere along the line.
