Intellipower Conversion Questions

Hi, I have a 1972 TradeWind that I am renovating. I am replacing my Univolt with an Intellipower 9245 and also adding a DC fuse panel. My questions concern some Univolt wires. I have attached a schematic of what I am doing and would very much like any feedback as to the correctness of my plan. I have listed my questions on this schematic attachment. Thanks for any help you can provide. (I've also read as many posts as I could find, but haven't found answers to my questions.)

Vintage Trailer Supply's website has a very good schematic for hooking up an Intelipower ,you might want to check that out.

Some answers:

1) with the original wiring, the white wire connected to one side of a shunt, which created a small voltage drop for monitoring the current flowing in or out of the battery. If you're not using a shunt (you don't want/need the amp meter in the panel to work), connect the white wire directly to the battery ground.

2) The blue charge wire from the car should connect through a fuse on the panel (20A is typical) to the DC + buss in the panel. The fuse is critical, since it prevents disaster if the car/trailer wiring shorts to ground.

3) You should use a fuse or circuit breaker rated for whatever wire size you used (typically 40-50A) as close to the battery as practical.

Remember, the battery will provide virtually unlimited (well, unlimited compared to the capability of the wiring) current. You want all the wiring to be protected in case something goes wrong. In this case, limiting the total current from (or into) the battery to 50A protects the battery wires, fuse panel and Intellipower wires (in case they ground between the panel and the Intellipower).
