I have had no time to work on the project but here are the things I will be doing next:

1. Swap engine pulley for same size as PMA (1:1 ration)
2. Attach Siemens enclosure with 60A (AC) circuit breaker to PMA output.
3. Attach SB120 power cable (pigtail) into Siemens enclosure and to 60A circuit breaker
4. Attach hour meter to engine.

I have to fabricate several SB120 cables, all of the below are using 6GA RED/BLACK ZIP CABLE.

1. SB120 pigtail from circuit breaker (2-feet) SB120-WIRE (permanently attached to dc generator circuit breaker)
2. SB120 extension cable (9-feet) SB120-SB120 (connects generator to battery pack)
3. Battery Pack to SB120 (5-feet) SB120-5/16" BATTERY LUG (permanently attached to battery pack, left dangling underneath cabin near access door)

The plan to use this here at the observatory is to wheel up the DC generator, open a small access door and plug it into the cable coming down from the battery pack. The cable #2 will stay with the generator. I will eventually make SB120 pigtails and permanently attach them to truck battery. I will also probably make a set of heavy duty jumper cables that I can use to jump start vehicles with the dc generator as well.

I have all the parts I need right now but no time.

I have replaced the engine pulley with another that matches the PMA pulley diameter achieving a 1:1 ratio. Just for documentation purposes I am using an A-24 V-belt. I am pleased with the amount of free adjustment that size gives me during the lifespan of the belt as as it stretches I should be able to compensate for quite a while.

I need to fabricate a control panel that will hold the hour meter, and I was thinking about mounting the breaker directly on the control panel along with the SB120 Anderson connector. I am going to use red connectors and have already ordered cable and the connector kits. They are rated up to 120A so perfect for my use.

Engine Hour Meter

Here is the Honda GX-160 schematic showing where to attach an hour meter. The type of hour meter I am referring to is the basic kind that merely records the time voltage is supplied to the positive input. In this case the voltage is +12VDC. I will cut and splice the hour meter into the wiring harness on the black and red wire from the switch to the positive (+) input on the meter. Essentially what this means is that the hour meter will always be incrementing whenever power is being supplied to the ignition coil.
