Folks,
Anyone got any ideas on the following observation.
I have noticed a recent chance in my on board voltage.
The voltmeter used to read 12.7 (approx as its an analogue meter) volts all
the time and never really moved that much that I ever noticed. Now it is
reading much higher 14-15 volts on the gauge.
I put a digital AVO on to get an accurate reading and I'm finding the
battery is reading 12.9 volts when off load and engine off. With the engine
running its reading 14.2. My interpretation of this is that the alternator
is permanently charging the battery and therefore overcharging.
The previous owner did say that the regulator had blown before and if I saw
more than 14v then pop out the Alternator field fuse to stop the battery
overcharging then fit a new regulator.
I have fitted a new one and its no different so I'm wondering what might be
going on.
This does coincide with me fitting a new intercom and GPS tot he panel and
while carrying out a few jobs on the plane I did inadvertently momentarily
short out the battery. Hence the reason I thought I may have damaged the
regulator/rectifier.
Any ideas please? Subaru not Rotax.
For any Subaru owners make a note of the following part number for the
rectifiers as it will save loads of searching when you need one!
Alt is off a Suzuki Swift car 1.0L & 1.3L. Nippon Denso 100211-2200 or
Suzuki part no 31400-82110 cost 35 inc post and vat. or you can pay 231 at
the Suzuki garage if you prefer!!!!
