Thanks for the info. I posted quite a few months ago. And it's now all fixed and up and running beautifully (touch wood). I broke the led removing the bearing. Got a bit carried away. But like you say it is easy to replace, just get the polarity right. The assistant at Jaycar Electonics was very helpful. It's great to go to a store where the electronics
assistant knows something about the subject. I installed a white led that lights up red when the Airex is functioning. This is much easier to detect a problem.
asks about the potentiometer. I don't really know if it can be replaced or not but what I do know is that the symptoms you describe occur if the wiring
is not correct. If the airex regulator
is detecting higher voltages because of other charging
sources ( such as a solar
panel). It tries to start up, detects higher voltages and then switches itself off and keeps cycling that way until it drives you insane. Try wiring the wind generator
directly to a battery
, with all other wiring removed and monitor
the voltage. Of course if the test battery
is already close to fully charged/ or shorted you will get the same result.
Before I put my Airex back on the boat I used an electric
drill to fire up the generator
( remove the blades first) and wired it up to my car battery in the garage using some jumper leads. I used a cut off allen (hex) key. The led lit up ( about 600 rpm
I think) and voltmeter showed my car battery charging
. So i knew the unit was working before I installed it on the boat.
Don't know if this helps but my point is to make sure the problem is the potentiometer before you start pulling the Airex apart.
