(First time poster - Hi all & apologies for resurrecting an old thread!)
Bought our first Hymer couple of weeks ago - it's a 1992 Hymer Camp 56 LHD German imported at some stage.
Am still familiarising myself with its systems and tracking back over years of mods/add ons going over how stuff works & what doesn't work.
The leisure battery mains charger is a Elektromatic LA110K & was not outputting any voltage at all.
A very quick look today I found the internal transformer fuse blown - replaced it & still no output.
Is it worth getting this charger repaired? I know it is the original as fitted.
But I have to replace the ~10yr old leisure battery anyway as it is only charging to 10.6V; would I be better to fit a more modern multistage battery charger at the same time to maintain the new battery(s) in prime condition (with perhaps an integrated solar PWM controller to give future options)? While solar is not a pressing need for as, there already is a (non working ~3V) solar panel fitted on the roof. This solar panel seems to have been wired directly to the output terminals of the LA110K???? - The charger says Solar on the front plate & there are 2 sets of +/- terminals; one set going to leisure battery, one set direct to the solar panel.
Is this a common setup on these?
Also, I am considering 2x Trojan 105Ah in parallel; is this overkill? Would the old Fiat 2.5D alternator handle charging them?There was another 45aH general battery added in parallel to the 96Ah leisure battery at some stage (2010); can't see that setup having worked very well.
Any advice you guys can give would be greatly appreciated & may save early mistakes in choosing something unsuitable.
Also if anyone had the electrical drawings of the Hymer Camp from this date or something similar.
Thanks
Lots going on here. Question - how do you plan on charging your two new Trojans. The Fiat alternator should(cabling!!) handle charging them but you'd probably have to drive twice around Ireland to get anything decent into them. I would think ditching the Elektromatic LA110K would be the first step. Then if you intend being on hook up all the time replace with something more modern - don't know what's out there - my van has a Sargent PX300 which is multistage but only suitable for leadacid. There are others on here far more knowledgeable than me who will likely suggest something(and correct any bad advice I give!!). If you will be mainly off site then a B2B and/or solar with a MPPT(rather than a PWM controller) would be needed.
Don't understand you wiring - pictures help a lot but I'd suggest disconnecting the solar and testing the voltage when there's a bit of sun around. If you have a working panel then something like a Victron 75/15 is relatively cheap and does a great job.
I'm only scratching the surface but hope it starts something for you
