Been having trouble with my dual batt not charging for months now. It also consistently clicked on and off repeatedly.
I thought my rewire after the rebuild was wrong or my batt was dead or my isolator died. I threw it on the trickle charger and it took a charger fine. Only problem is when the isolator linked the 2 batts didn't actually link an charge my 2nd batt. When linked it evens out the voltage.
I took out my power probe and started diagnosing. Turned out the higher alt voltage wasnt making it from 1 lead from isolator to aux batt positive. I took out the aux cable positive wire. Batt side came off fine. As soon as i touched the isolator end it broke apart and disintegrated.
I usually use solid copper wire but I ran out when I put my system together. So I used some copper clad stuff i had laying around. Note to self. Never use that copper cladded crap ever again. It's as good as garbage.
