I had trouble with the original contactor after I installed the 160 amp alternator so I decided to upgrade to a 200 amp system. I also wanted to do away with the power consuming main contactor for coach power. I made up a complete panel that controls both the house power and the charging connection to the alternator, I have no isolator (never did have one), just a contactor that closes when the alternator is producing voltage and the main buss voltage is over 13.2 VDC for 2 minutes. This is also a bi-directional system so that when I am charging the house batteries, if they are over 13.2 VDC, the contactor pulls in and the chassis batteries are brought on line for charging as well. The system uses the Intellitec "Big Boy" contactors, house power is a latching and the other is controlled by the Intellitec "Bi-directional Isolator Relay Delay Diesel-2" system. Will be on the road tomorrow and see how it all goes!

Replacement DC panel

That looks like a really nice job, Ed. I have a deep appreciation for how tidy you've kept what I would have turned into a rat's nest. Certainly goes beyond my electronic abilities Smiler

As an aside, I drove a Mack the other day and blew a 'fuse' for the taillights. When I opened the fuse panel, I realized that it didn't have fuses in the traditional sense, but instead it had small circuit breakers. Sure enough, a little while later the 'blown' breaker cooled down and started powering the lights again.

My question is, have you or anyone else here used something similar in the fuse block of their coach? I'll probably end up doing some wiring again at a certain point, and it sure is nice to not have to root around in the bottom of the glove compartment to find a suitable replacement fuse in the middle of the night.

My Barth has automatic reset circuit breakers all over it. Behind the grille, inside the genset compartment, etc. Auto parts as well as RV stores sell them.

And I will echo your compliment on Ed's good looking installation.

Ummmm, not yet, thanks for the reminder!

I will try to get that done next week along with a schematic of what it takes to put a GM electronic cruise control in the Barth.

The radiator job along with all my "honey do" projects, took a lot of energy

I'm impressed, just wonder about the cost. I buy my parts in Canada and always feel I.m getting gouged on this type of purchase.
