Daox · 06-13-2009, 10:47 AM

Since I've been looking into going alternatorless, I wanted to do some testing to see how much amperage things pull on the Paseo. The first test was the biggest amperage puller I can think of, the starter. The initial setup is the picture below. I'm going to need something a bit more permanent to use while driving down the road.

Anyway, the starter pulls a very quick 125A (for maybe a half second) and quickly settles to 100A. I pulled my spark plug wires to do the test. I also used the 200A ammeter from Ben Nelson I got for my electric riding lawn mower. I was worried (and rightly so) that using a standard 60A automotive gauge might fry it.
