Allanson D40-BRA-E Converter

[mr-moe]

Have a 1988 Royal Industries, Royal Classic 31 foot. Fine machine.
Would like to find operating info and circuit diagram for above converter.
Does not charge house battery.

Thanks
Moe

Have you tried contacting Allanson to see if they have any information available?

(Though I do agree that replacement with a modern multistage converter, maybe something like a PD 9200 series, would be well worthwhile. There would almost certainly be a noticeable improvement both in the time required to recharge the batteries when low and in the longevity of the batteries when the RV is plugged in long-term.)

If the converter is that old, I think you should look for a modern unit with the advanced 3 and 4 stage battery charger that works so much more efficiently.
