Electrical Output-582

[Smiley]

Hello everyone

What should the electrical output be on a 582?
Where can I measure this?

My battery is not charging anymore and the volt meter is running “low” when all instruments are switched on or off including strobes.

This used to be no problem…

Here is a doc that describes the whole process

In short the charging voltage should be above 13.5 but below 14

Thanks, I'll read through it tonight!!

It's usually the regulator. Borrow one from somebody alse to test it

You can buy the original from Aviation Engines or an equivalent from Amptronic +27 (0)11 679 27 54

Hi Smiley,

The fuse holder from the regulator to your battery positive also frequently give hassles - I replaced one on a trike last week-end (sometimes the spring inside wears/slacks and they don't make contact even if the fuse is OK. You can also check continuity of the lighting coil (The resistance between the two yellow wires coming out of your engine - should be about 2-5 ohm).

Like Morph said - first step is to check your're getting 13.8 volt on the battery while the engine is running (rev it a bit - some regulators need a bit of revs before they start charging)

Check the leads too - found on one aircraft one of the leads had carbonised (dont know what the proper tech term is) and the resistance created by this basically made the whole system inoperative. Only way that we found that was once the casing had been stripped off the wire completely. To test use a new set of leads from the regulator and see what output you get from there.

Is it possible to start the motor and loosen the possitive terminal and check the charging rate between the batt pos and the terminal cause i cannot determin if the batt is on its last or if it is the gene

[Morph]

yes, the motor won't stop if you disconnect the battery. The battery is not required to run the motor, just to crank the starter motor

[BOATCH]

[KFA]

Just check. There is a minimum voltage requirement for the system to charge.(some systems). usaully in the region of 1-5 volt

[BOATCH]

That is why i am thinking to check the amps rate on the batt because i have a red light that shows when the ign is on i hope that will be sufficient and i can still switch the radio on for more current

Just be careful, most regulators don't like being disconnected while working, it could be the end of it

With the battery disconnected, and it standing for a while (like overnight) you should measure at least 12.8v on the terminals, 12.6 is considered flat, if the voltage is a lot below that (like 2v below) then you might have a dead cell. With the motor running you should see at least 13.6-13.8v, if it is below that the battery won't charge.

If you want to check the amperage that you are charging at while the motor is running I would suggest you start the engine and then before you detach a pole first connect a piece of wire, with 2 crocodile clips, between the cable an the pole, you can then remove the cable, insert the current meter and once the current meter is connected you can remove the wire with the crocodile clips (at least one side). This will prevent any damage to you regulator by preventing a spike. Follow the reverse to reconnect the cable or shut down before doing it.

Good luck!
