I didn't read all of these postings, my head is not my own this AM, but one thing I would think running a high numerically numbered gear set, low gears, would allow the pinion to turn faster than than the wheel rpm, 7.5" Diff may not handle a very low ratio so an 8.8 might be better.
The pulley size, to me I would measure the Crank Pulley and the existing Alternator Pulley and determine a standard ratio.
Then determine your usual cursing speed and the RPMs of the Pinion Shaft, from there you can determine the pulley size and ratios to get the Alternator up to the desired RPMs to make electricity, also there may need to be an exciter wire to get the alternator charging, maybe a running light wire could do it !
Was just thinking... SMOKE, if you mounted the Alternator stationary under or in the trailer and used a drive shaft, which would be at the same rpms of the pinion, with a Drive Shaft Support and Pulley arrangement, you wouldn't have to worry about any suspension woes.
I curse at all speeds Sir.... A L L Speeds....... lol
I did think about the pully dimensions, but then I started thinking about the speeds and wasn't sure If I was on the correct path.
I'm just thinking on the run.
You need to know at what rpm the alternator will produce the amperage you need.
Then you can work backwards to the speed of the pinion shaft and size the bullies from there.
Probably isn't as easy as I'm thinking, but I like the idea..
It will be interesting to see how you handle this, definitely something to think on !
Also, how do you intend to mount the Alternator, it would take a beating on the axle, I would think it should be mounted to the frame with a driveshaft.
Anyhow..., make sure to post, I would like to know how this turns out !
