In an earlier video I assembled a DC generator to run from a Honda GX160 engine. It's been so useful since that I've rebuilt it with some upgrades.
There is a new custom carry-frame made from 1/4 inch steel plate and some BSP pipe fittings (thread-locked solid). The belt drive is now a chain drive and the dynamo (motor) has been changed for one with holes in so that it runs cooler. The fuel tank has been changed too.
This video is it's first test. I plug it into a massive 12v battery (1500AH) that's only 1/2 charged, then start it up.
As it's a DC motor, I don't need to pull-start the engine, it starts itself just by connecting the battery to the jump leads.
With the engine idling it was making about 15 amps but after progressively cranking it up, it was putting more than 90 amps into the battery.
The dynamo/generator is actually a 24v DC motor made by Bosch that I got cheap off eBay. Apparently these specific motors are becoming sought after as motors for electric bike conversions and go-karts but there are loads of other suitable motors around that would also work well.
