Hi folks,
So I was driving home last Thursday night and I got the multiple warning lights issue that a number of people seem to be having lately. (battery, cat, rear lights & oil level). I checked the voltage across the battery and sure enough, there was no increase in voltage with the engine running and revving slightly.
Was booked in for new timing belt & brakes on Friday, so asked the guy to check the alternator. He pulled it and sent it next door to an alternator specialist, who said it was goosed and supplied a new Denso unit. Got the car back with everything looking good!
While out for a drive yesterday, I noticed a slight whine from the engine bay. A short while later all the warning lights came on again... Pulled in, switched off and checked under the hood. Burning smell in engine bay, coils in alternator had gone from brown to black.
Went to restart and found that the car was dead. No ignition lights, nothing. Hooked up the GF's car to jump start and some grease on the cable clips started smoking. Unhooked the +VE lead from the alternator and turns out the alternator was shorting the battery. Was then able to jump start the car but not enough battery left to keep it going.
Probably not relevant, but a few weeks ago I replaced the thermostat, plugs, HT leads, dizzy cap and rotor. Also, mechanic said that the old belt tensioner was in a bad state and the old timing belt was a bit slack...
So, any ideas what might be causing the car to eat alternators? Will do tippex test and check aux belt this afternoon.
Cheers,
Andy.
