MWR and QLR generators

On the assumption that you are referring to the auxiliary generator and control box, I don't know about the MWR but the one on the QLR is shaft driven from the PTO on the transfer box.

On a QLR the axillary generator was shaft driven from the PTO on the gearbox.

Gents, thanks for that - I was leaning towards QLR it confirms what I originally thought. I'd also seen a photo of a QLR generator with a pulley for belt drive on, which is partly what threw me.

If these are a pair as I was told, I guess the 'for D5LA-26X' is a red herring and the 141 control box was also used for the DW7X8X? Or these are in fact from two different vehicles?

The axillary generator on a Bedford QLR is DW7X8X and match bigger than the D5LA-26X , they use the same 141 regulator.

picture is from a MWR axillary generator.

...they use the same 141 regulator.

Ah, this is the crucial point. Thanks, that confirms they are a pair then. Not that I actually have a QLR for them...

Thanks for your help, chaps.

Need to double-check what I have here just to be sure.

Guy said in this thread:

The auxiliary generator on a Bedford QLR is DW7X8X ... they use the same 141 regulator.

However in another thread, someone asked about this control box on a QLR that Peter Hommes had for sale:

... It's clearly a 141, and given the discussion here I said it was the control box for the [DW7X8X] auxiliary generator. Guy replied:

Sorry, but the big box on the rear of the cabin is the vehicle dynamo regulator box for a wireless equipped QL. The chassis and the remaining bits are from a QLR , so on the chassis normally you had a radio box unit.

...which I took to be stating it was the regulator for the vehicle (i.e. engine mounted) dynamo NOT the auxiliary (chassis mounted DW7X8X) dynamo. This appears to contradict what was said in this topic, so I'm now confused.

Though I know nothing about QLR auxiliary charging, all the FFW / FFR vehicles I've come across with auxiliary dynamos have a conventional control box for the vehicle dynamo and a large auxiliary control box either in the cab or in the radio body. The box in Peter's photo is clearly a 141 and so wouldn't appear to be the control box for the vehicle dynamo.

I'd like to clarify so I know definitively what I have - is it definite that the 141 is the control box for the DW7X8X and that the pair formed the auxiliary charging set on QL®?

Thanks.

Sean,

According to the manual, the controller on back cab panel is a 142-1 and is the engine dynamo control board. (this appears at a glance to be a 141, as it is a similar casing)

It says the Auxiliary board, 141-3 is mounted 'in the front bulkhead between centre and nearside ventilator' so points to it being in the body.

cheers Richard

Richard, thanks, that's interesting. Having had next to nothing to do with them I hadn't realised QL® had such a control box for the engine dynamo, so that's where my confusion arose.

Having the auxiliary control board inside the body on the front bulkhead is consistent with practice in other vehicles so sounds probable.

That confirms Guy's comments and that I have a QLR auxiliary charging set up. Thanks.

Guy, thanks again for your input on this.
