When installing ZIG unit does the main and leisure batteries have to be directly linked together or is the leisure battery charged purely from the ZIG eliminating a heavy cable from main to leisure battery Thanks for any info......BRUCE
best to use a split charge kit to charge your leisure battery while driving, the more expensive 70 amp ones are better, KING OF ENGLAND on here is the man you want, he wired all the electrics up in my camper/dayvan, a very tidy job for a good price aswell, he really knows his stuff
