Heavy duty split charge relay. Ideal if you're using a second battery to power camping equipment, lights or a sound system. Controlled by microprocessor, it connects two batteries in parallel, automatically disconnecting the main battery when it reaches a pre-set, full charge of 13.2v. Then, when the charge drops below 12.8v the split charge relay reconnects to allow continuous charging. In this way, both batteries are continually topped up.
no 103 Glow plug relay. Fits diesel T4s from 1996 to 2003, and T5s from 2003 to 2006. Problems starting up in the morning? If your glowplugs are working properly, a possible cause is a faulty relay.
