So my snazzy BandC voltage regulator is outputting a bit of AC and getting hot. To be fair “newish” means 3 years old. The BandC includes and OVP unit. I am assuming that this is a manufacturing issue since this was one of the first produced.
So my question is who has overvoltage protection AND expensive avionics?
I had an old style OVP with a relay/crowbar etc which I stupidly trashed when I got my new BandC so I cant simply put it back in.
So should I put in my old but (fully functional) rotax regulator and fly without OVP pending the arrival of my new (and hopefully improved) BandC or just be patient….? (My name is Will and Im a flying addict)

4-5 volts and one of the outputs is a bit burnt - heat shrink melted

Radio Noise
If you are getting radio noise that seems to be alternator-related, you can use your multimeter to do a quick check of the alternator output voltage. Set your meter to AC voltage and measure from the main bus to ground while the engine is running. If you see more than one volt in the AC scale, suspect a blown diode inside the alternator or possibly bad brushes. Remember, the alternator is only supposed to output DC voltage. This isn’t a perfect test, but it is quick and easy. A ripple meter is an even better way to check stator and diode condition, but most amateur builders will not have one in their toolbox.

Ill be calling them monday - just checked the installation date and it was Nov 2021…so lasted a year. They normally produce good kit so this must have some kind of an issue.

Hi! William /All.
When I had G-PTAG Three times on inspection I found that the continuation connectors from the alternator standard Rotax wires where I had a rubberlite connection assembly taking the electrical power into the panel/regulator I discovered the lot all heat welded together.
I found that the spade connectors did not have sufficient contact area and were arcing generating heat from sparking . I didn't find a solution to the problem which was initiated by Rotax using spade connectors on the power delivery spades which only have knife edge contact area . Some form of screw clamp connectors would generate less heat from arcing , which in turn would remove radio interference and potential for fire.
regards

Spade connectors of that size are rated to 10 amp and 300v according to the R/S-Components specification sheet.

I hear what you say but the nature of spade connectors utilise a knife (male) connector into a female receptor and they can spark.....I've seen them arcing .....put your head in the sand and ignore it at your peril. The reason I had three examples of molten connector assembly speaks volumes, not withstanding the original "posting on subject" reported the same issue. In test conditions the connectors may be adequately rated but subject them to vibration and that rating is obviously open to question, in other words "they are shit".

…and why assume that the BandC is delivered with plated (i can’t remember with what) replacement connectors in an attempt to carry more current without overheating, per their instructions.
I have no idea if they are effective, but mine are not (yet?) charring fwiw.

Hi! William /All.
When I had G-PTAG Three times on inspection I found that the continuation connectors from the alternator standard Rotax wires where I had a rubberlite connection assembly taking the electrical power into the panel/regulator I discovered the lot all heat welded together.
I found that the spade connectors did not have sufficient contact area and were arcing generating heat from sparking . I didn't find a solution to the problem which was initiated by Rotax using spade connectors on the power delivery spades which only have knife edge contact area . Some form of screw clamp connectors would generate less heat from arcing , which in turn would remove radio interference and potential for fire.

Radio Noise
If you are getting radio noise that seems to be alternator-related, you can use your multimeter to do a quick check of the alternator output voltage. Set your meter to AC voltage and measure from the main bus to ground while the engine is running. If you see more than one volt in the AC scale, suspect a blown diode inside the alternator or possibly bad brushes. Remember, the alternator is only supposed to output DC voltage. This isn’t a perfect test, but it is quick and easy. A ripple meter is an even better way to check stator and diode condition, but most amateur builders will not have one in their toolbox.

After a little research I think I now know what this thread is about and have a couple of questions.
1. Is this a straight replacement for the Ducati units?
2. Does the ducati unit contain OVP?
3. I have just fitted an Earth X battery (but not yet run the engine), will this charge OK using the original Ducati regulator?
Sorry for my electrical ignorance.
Cheers

1 - yip!
2- Nope
3 - it may? but the BandC has an adjustable/settable output for the higher requirements of the EarthX

I have an EarthX and the Rotax Ducati Regulator. It charges the EarthX and not had any problems.

Ducati regulators vary. My last regulator's output was 13.79v, which was not enough even for a Red Top battery let alone Lithium. Fairly easily fixed though.

Thanks chaps for the replies I now have a better grip and at least know that it shouldn't blow up upon engine start.
Duncan, you mention that a low charge rate was easily fixed, can you let me know how?
Thanks
Mike

The bandc charges as 14.4 volts from the box but is adjustable and does have OVP built in.
Plugs straight in.
It's a lot nicer looking than the rotax item but costs USD300....
