B and C Regulator now replacing the Ducati?

[allbee]

I took my Ducati out and replaced with the BandC couldn't be happier. I called the tech line and was told just remove the connector and plug it right into the BandC. Charging great, at the same time I put in a EarthX and wired in for a light on the dash, I got all that from BandC as well. simple install and working great. 912uls. I have both the regulator and the battery behind the firewall NOT on the motor side.

Hi All
I have a B+C regulator (PN: XB100-1).
It was installed on 10/10/2022 and failed on 9/15/2023 at 85 hrs.
Correction: installed on 3/19/2021 and failed on 9/15/2023 at 85 hrs.
Not charging at all and its is "smoked" (burned smell and one connector).

I put in the OLD Ducati but it only charges at 13.6V and 2A (full elec load @4000RPM).
It will do for now (plane parked) till I figure out what happened and what to purchase.
I have a call into B+C to figure out what happened. Not looking for free anything just what happened and how to prevent it.

Comments?!?

If you burned a spade connector, perhaps it wasn't a tight press fit on the the VR terminal and thus a source of resistance / heat...

Many thanks!
Both connectors "looked" tight and were a PITA to get off.
But on the B+C side it looks like the plastic was melting got the 2 Gen connections. Could the Gen be putting out too much power?

I also had a burned connector due to limited contact with the B&C pins. The Ducati connector housing is an interference fit into the B&C regulator. I discarded the connector housing and plugged each pin fully onto the regulator tabs.


Working great now at 14.1 volts.

No, the current is limited by the aircraft load. The generator will put out whatever current that the load requires, up to the maximum of the generator's capability (about 20 amps). The voltage is limited by the voltage regulator. Melted plastic is caused by heat from a loose connection.

When I removed the connector (the holder) it was a PITA. So not sure if the connectors were lose or not. Either way I replaced all the ends and wrapped them and installed on the old Ducati for now. Nice and tight!

EDIT:

Why is the old Ducati VR $175 and the B+C $345?
Since my B+C is toast do I hunt down a Ducati for less or suck it up and get a new B+C?


Spoke with B+C and they will test it and fix if they can.
I'm good for now. May thanks to all of you for your thoughts.

I just replaced my Ducati at 700 hours; about 200-250 hours per unit. I am able to replace myself (two left hands) in about an hour, all for $175 plus tax. For me, that is the easier answer for the problem. The Ducati remains a simple plug and play replacement for the mechanically challenged.
