I just finished installing Peninsular Diesel`s adjustable glow plug controler. It`s getting cold up here at 9000ft now so hard starts are getting to be part of my morning. The controler is timeable so that you`r system will produce only the amount of glow plug tempature that you`r engine needs. I have alread seen a improvment in cold starts. You can reach Peninsular at www.peninsular engines.com. Sorry but I don`t know how to do those cool links that you guys are always putting up.
