no you do not need the iah. you can disconnect one battery and unhook one cable from the other and hook a test light to the post to the clamp. it will light up. start pulling fuses one at a time until the light goes out. when you find the rite fuse you will know what circut is draining the batteries

Take your battery's and have them Load tested. one battery probably has a dead cell and is draining both. It dose happen often when one go's bad. sometimes It will show 12 V by just doing a test. that's why it needs to be a load test.
it's a good chance the short and battery drain killed off a weak battery, you can NOT test both at the same time. you need to do EACH Separately.
