The small case (cs130) alternator I replaced can be found in higher amperage,thus avoiding the cutting and welding. But there are reported cooling /reliability issues with the higher amperage small case versions. That is why I went to the larger case Delco. I also wanted to be sure if I have a failure on the road I can get a alternator that fits from any auto parts store.

The piggy backed wiring to the battery was recommended by the manufacturer who said the two together would approximate the capacity of a #2 wire.

I am not sure of gauge wire Beaver mated with my 1991 factory 160 amp alternator & giant battery bay. Did not check so i am kind of a science experiment. Current 270 amp QP alternator will put out some serious juice so if i burn up this thread will be revisited!!

Our Leece Neville 160 Amp unit went out while on a trip. Did not have time to send it out to be rebuilt, so put on a new unit. Several members of the CC Owner's group had changed over to the Delco Remy 200 Amp unit. I went with the Delco 200 A because it was available 30 minutes away from where we were camping, and the price was not bad either (I believe around $265, but would have to dig in receipts to see if my memory is correct.). I took my Leece Neville with me, and we compared the two on the bench before I purchased. They even swapped the pully over for me.

Had the Leece Neville rebuilt when were done traveling, and sent it to a friend for his coach when his went South... He had his rebuilt also, and has it available if I ever need it!

I think that was a great tip from Twinboat to check your wire size, to be sure it is adequate for the higher loads...

By the way, I feel 160A was more then sufficient for what my unit was asked to do... But OK with the 200A too!

If I change to lithium battery bank in the future, may look into changing the Alternator again too... We'll see!

Best to all,
Smitty

My Mechanic says my cable is 2 gauge (standard on big rigs he says) and told me it should be penty to handle the new alternator

More facts. My Batteries in the front of the 40' coach are connected by massive cable to starter... in back of coach. Alternator has 2 gauge cable running short distance to starter. I think i am ok
