Posted: Mon Feb 13, 2023 6:27 pm Post subject: No charge lamp stays on

Hi Folks,



Started my 912UL today (first time for 2-3 months) and it started first 

time! However, I noticed that the 12V 'no-charge' lamp (connected to the 

rectifier pins L and C) remained illuminated indicating no charge.



I ran the engine a while to get it up to temp but the lamp stayed on and 

after shut down my battery voltage had dropped below 11.5V. so it is 

definitely is not being charged.



I'm sure it could be a number of things from a dodgy rectifier to issues 

with the alternator.



Any pointers as to what to look first at would be appreciated.



Regards,

Martin Tuck

Hi Martin,     

I'd first check actual voltages with a reliable voltmeter, then       perform a serious check of the wiring and connections.

          

Did your alternator charge before? Did you disconnect/connect anything       since last time you ran the engine with no issues?

Thanks Giles,



I haven’t done anything to the aircraft since the last time I flew and all seemed well then. I found a good video on troubleshooting the system on the Rotax Owners site so I’ll be looking to perform those checks and see what might be going on.

Which video Martin (link or vid ref number)? 

 

 I thought I'd watched them all, but don't recall one on Reg/Rec or charging troubleshooting...!

I had the same issue - Bob Nickolls said that the charge light system in the Ducati regulator is very primitive and not to pay attention.   A reliable voltmeter is required. 

Eventually my charge light went out by itself.  The battery charged just fine while it was on.

William and all,     

Agreed.     

First measure actual voltages.     

Yes Bob Nuckolls on http://www.aeroelectric.com/ and on the 'List       is key.

I would imagine you can tell if it’s operating properly if your panel voltage reading prior to start is about 12.5volts and with engine running (charging system working properly) you should see about 14.8volts.
