Hi all, not long bought a 1989 Hymer B534 It came with a solar panel fitted to the roof (no paperwork or manuals) so the only detail i can give you is its measurements (if that helps) 42 1/2" (1080) long 26" (660) wide 1 1/4" (35) thick. Ive followed the wires and it is connected straight to the lesiure battery. I have just replaced this battery as the one it came with was dry as a bone and Knacked. My question is (1) should it be wired to a regulator then to the battery and (2) could the fact the panel is wired direct to battery have caused the old battery to dry out or is it just that previous owner wasnt hot on maintenance. Have looked through loads of threads but as of yet not found an answer.:Sad:
