Onan BGE charging circuit

We have a 88 Holiday Rambler wt. an Onan 4KW BGE. generator. (spec.C) 4.0 BGE-1R / 26100C serial H870918582 (Aug. 87)

I read an article about a potential problem (several years ago) with units prior to spec. G where the charging bridge could short to ground and damage the B1 and B2 windings. Ruining the rotor.

The note I copied mentions disabling the battery charge circuit as it is redundant. The converter charges the batteries at a much higher rate (and new models are 3 stage).

The article mentions CR10, the charging rectifier and the R6 charge limit resistor.

My manuals do show R6 but have a CR 1 in the charging circuit. The only bridge rectifier feeds the voltage regulating transformer.

I haven't torn into the circuit box itself to see if it agrees with the circuit in the BGE manual.

As the article has no reference or names I don't know where I got it. The old selenium bridges were four square plates with terminals in between and a mounting stud (ground potential) that went through the center. That is the kind of rectifier I would assume could short. The newer semiconductor ones just have four leads and no ground path.

I didn't find anything on the forum about the above. If anyone is knowledgeable, please advise.

Thanks, Jim

Onan PM

I recently purchased an 89 class C 27' with an Onan genset on board. Not sure of the model or SN, but I'll check ours for problems once I service it. Thanks for the tip!

Please do. I have all the manuals. Operator which came with the coach. Parts, Install and Service which I bought from Cummings. They seem to take a beating and keep on ticking. )

Thanks, looks like a great resource. I have two Honda, 2 - 3 cyl. diesel Kobota and the Onan generators plus a 13 HP Honda pressure washer. I wrote to Generator Jim concerning my original post as I suspect what I have may be mixed information for the Marquis 7KW and the BGE?

He promised to look it up when they get home from camping.

Will post what I find out.

Thanks again for the link to Smokstak. Will spend a lot of hours there.

Jim

BGE charging circuit

I have confirmed the information I had on shorting charging circuit failure applies only to early Marquis 7000 units and not the BGE gererators.

Sorry for raising a bogus question.

Continuing to repair hail damage to the coach and renovate everything that has been setting waiting for retirement.

Received a new AC shroud yesterday from Canada. Have new vent covers and caps to replace the broken ones. Decided not to replace the pod for now. Just don't think I have any business up there on a regular basis. Don't want the DW to have to push me around in a wheel chair for the rest of my life. Maybe later after dropping 50#. )

The cover was broken on the bat wing TV antenna. Been looking for a replacement wt. high VHF and UHF for it. We use it for local only, have a DirecTV antenna for most watching.
