I have a 2 alternator 70 amp 3 battery isolator ( 2 70 3) It says maximum 70 amps on the sticker. My 2 engines have alternators that put out 55 amps according to there tags on the sides. My question is where it says the max. on the isolator is 70 amps does this mean per post as it has 2 alternator input posts. OR Does it mean total of the 2 alternators input should not go above 70 amps combined? The original is defective and was in the boat last year when I bought it. When tested power was able to go both ways through the diodes and it wasn't doing the job anymore. I have searched high and low and cannot seem to get an answer on my 70 amp maximum issue. Any input would be appreciated. Furface
