I'm going to switch to an alternator and have been looking at the various kits .As I have most of th parts the kits seem a little bit of a waist of money.Also I'm concerned that the alternator in the cheap kits aren't that great although I won't be racking up many miles. I don't think I can afford a Bosch one but wondered if the Lucas ones are pretty good as I thought Lucas is a ok brand. Other than that I've seen a JP group 75amp job for sale although 55a would be find for me .
