Just my 2cents.... From what I gather from pics and description; You (hopefully) have the solenoid powered by a fused "ignition-on" source coming from the TIPM. If so; then whenever the Jeep is ON; the solenoid will be energized and engaged. Effectively joining the two batts together. Two potential problems here. One... the alternator will constantly be trying to charge both batts = hard on the alternator. Two... the solenoid must be rated for "constant duty cycle"; or it will burn up in time.
It sounds like, after a new solenoid install, all is OK for a while; and the solenoid burns up. The beauty of the "smart isolator" is that it only engages when one of the batts drops below a predetermined level. Thereby, saving wear on the alternator. Benchmark-design's solenoid is rated for constant duty even though it never works in that situation.
Additionally, the solenoid will get hot when it's engaged. Locating it above the batts will get it away from the exhaust headers; where it is currently being radiated with intense heat. The poor thing never gets to cool down!
So... Replace with "smart isolator"; and move solenoid (isolator assembly) to cooler location. Get some type of volt meter gauge to monitor your batt condition regularly. So far (1yr) my Benchmark-designs stage 3 dual batt system is working flawlessly. Thanks, John
