Not to long ago i replaced the glow plug relay on my 97 psd. Ever since then my batteries have seemed to be discharging. As long as i drive the truck every day i have no problem, but if i park it for a day or 2 i have to charge the batteries back up to start it. I guess my question is, is there a worng way to hook up the glow plug relay?
