Model PD9280A converter problems

PD checked both converters out. Both checked out fine. I received one back and installed it. Dennis at PD went the extra mile trouble shooting with me. Got consistent 120 volts at outlet converter plugs into (removed surge protector which showed some arching). 13.7 volts coming out of converter. Positive line running to battery compartment, hooks to a relay (I believe). The second post of the relay has a positive line running on to the batteries, with several other smaller lines hooked to it. Several years ago this thing started clicking. As it clicks the voltage at the battery posts changes from 11.3 volts to 12.5 volts, and back again. Is this caused by a bad relay? Called Jayco tech support and was told to take it to a dealer. My trustworthy dealer has retired and closed up shop, unfortunately.

I'm replacing the relay (shortstop 12v s49 50a). It's reading 13.7v at one post and 11.3v at the other.

Get rid of that fire starter. Replace with a 100 amp Hi-Amp Bussman.

80 amp converter feeding the battery through a 50 amp shortstop is only trouble.

Ok thanks.

I have only installed one replacement PD converter (a 9180 and I reused the charge wizard dongle)

NOTE with the 9280 you use either no dongle or a different one.

I do not know where you are but PD is located in Marshall, Michigan.

Google Maps: Brooks Memorial Fountain, Marshall MI
Then slide south to Industrial (road or whatever) not very far at all

They are on the corner

I'm in Maryland. Getting great guidance from Dennis at PD. Thanks

Per guidance from Dennis at PD, I am replacing the CB with a manual reset Buzzman CB 185 series 100 amp.

Thanks for all the help!!

I had the GOOD Fortune to deal with Dennis a couple years back on a new start camper build with LiFePO4 batt - He is a solid 100% EXPERT, so be sure and trust his sage guidance!

Agreed. Dennis/PD went the extra mile to get me straightened out. I recommend them highly.

Note when checking voltages in and out measure at the Converter's connections. If you measure 120 volt at the breaker.. that is no guarantee it is getting to the converter (I had that problem with my Air Conditioners. 120 volt at the termional on teh breaker, nothing on the wire stuck in the clamp as the screw was loose.. had it with my converter too, it was a 'P' Model (plug in) plug out.

Likewise measure at the converter, and the batteires. that would have found the problem "Downline" of the converter.

I also like to use test lights when I can rather than meters. Put like a one amp load on the line

Had one wire in my RV once 13.6 measured on one end. close to it on the other with the high impedeance meter... NOTHING with the light... Yup one solid length of wire The problem was about 1-1.5 feet from the battery... Cut and spliced and all good.
