Alternator repair

Coming back form the lakes I noticed the battery warning light flickering on the binnacle. I stopped and checked and the alternator was only putting out 11.72 volts grr. Luckily the battery was fully charged so I quickly diverted the leisure batteries to they would feed the engine battery and set off.
I phoned my favoured garage, GC Autos in Gateshead and he quickly had me booked in and a new 150 amp alternator fitted for £166. First class service from them as always.

I probably demand much of an alternator as I have a battery to battery charger. What this device does is it fools the alternator into thinking that the leisure battery is flat so that the alternator puts out it’s max voltage. The charger then checks that the engine battery is fully charged and when that’s done it starts charging the leisure batteries with up to 50 amps and 14.8 volts. So my alternator is working a lot harder for a lot longer than most.

That’s the second alternator and the van has done 130,000 miles now. The first one failed at year 2 and was replaced under warranty, so lets hope I get almost 10 years out of this one as well, especially given the work it has to do.
