We offer a number of solutions to solve your glow plug relay problems. BUT before you panic be sure to check the strip fuse inside the relay top cover. You cannot believe how many fuses Kent has sent with very fine hair-line cracks. They are not evern burnt so it is hard to see the failure. We also have manuals available to help you troubleshoot your glow plug related problems. So do a diagnosis BEFORE you order parts. If you are sure the relay has failed you can replace it with a quality Monark unit we offer or you can install one of our manual push button override kits.
