I have been following the website for about a month and finally decided to build the smack's design. I got most of the parts from Lowe's and set off to building.
Hardest part to find was the nylon threaded rod, which I ended up ordering from SmallParts.com. Got a 2 ft section for less than $10 with shipping.
I have not tested my output, but it looks pretty strong. I also have not tested the amp draw because I have yet to replace my fried multimeter. The unit got pretty warm after about 20 minutes of running, but definetely not too hot to touch.
Once question I have, how much strain is this going to be putting on my alternator. When i connect the leads, i can instantly tell a loss in rpms, although very very slight. Also when the leads are connected the alternator instantly starts sort of whining sound as if its under heavy load. Wont the extra load conteract any fuel savings the unit may achieve?
I have 98 Jeep Wrangler with a 4.0 engine. -
