Help, Im going to upgrade the altenators on my twin Perkins 4236 desiel setup. At present i have old very 35amp ones with separate rectifiers which leaves me with a mass of wires and a poor charging system.
What i would like is two 70-100 amp ones with built on regulators. I have it seems a choice i can buy lucas marine ones A127 70amp max with insulated earth returns that cost a fortune or hopefully someone on here will give me a cheaper option.
I cant see why insulated earth return is such a big thing, as long as there is a good battery to engine earth strap fitted, does that not mean insulated earth return is not needed?
Also can the two engines and the domestic battery share a common earth this would make life easier as all things would go to a shared earth post.
Now im a bit handy with with fitting stuff and i really want to do this myself two reasons firstly cost and secondly i dont always trust other peoples work.
So if you have any ideas or if some nice person has or would like to draw me a wiring diagram i would be forever grateful and a few beers will be purchased should we ever meet.
Any help or suggestions would be appreciated.
