Stangely mine started its life towed to my house. Then over the last 5 years has done more miles on a flatbed than under its own steam.
Any auto-electrical genini on here?
Right.
Vehicle 1973 Vw transporter (camper)
engine 1994(i think) subaru legacy 2.0l naturally EJ20 block.
[here is the bit where we ignore the people who fitted it in the first place – made an absolute balls of it and subsequently lead to another company having to sort it out and make it work. Which id did. For a week]
Drove fine prob 30miles in the week. Then sat did 20miles or so stopped at petrol station and wouldnt start, not even turning the starter. Jumped it start straight away rev'd up fine and drove fine. For about 2miles. Then revs dropping off and fianally dieing.
Again jumps starts fine, and idles fine – however put hazards / light on and engine starts to struggle idle poorly.
Mechanic put multi meter on it – reads 11.73v across battery terminals and the same from alterator to neg strap.
I was figuring dead alternator. However this has recently been replaced as had diff getting battery to charge. Had the original bench tested today and its working fine.
So this makes me wonder if there is a fault in the wiring to the alternator / regulator from the ignition loop.
This is supported by the fact there are only 2 wires coming of the alternator terminal (excluding main bat+ cable)
The connector has 4 pins – as it has been some what jury rigged to get it working (by v. capable mech) i dont know which terminals are in use.
the conector is Thus:
S D
IG L
S – Sense battery voltage
L – Ground to ingition light
IG – Ignition switch signal turns regulator ON
D – c**k only knows
So with only 2 wires im guessing they must complete the circuit from IG to L. Now im wondering if this means that the alternator doesnt sense the dropping battery voltage and that the alternator is sending enough charge to the battery. Or if the alternator would just feed a constant charge to the battery regardless of its charge state and that it is the alternator that is dead.
Any ideas?
