Relay Board Grounds
Posted: Thu Apr 11, 2013 12:30 am
Hi,
Please please help me with regards to the grounds on the relay board, having read a lot of great information there is one common theme about noise and that is that most grounds should go separately to the engine block.
However, I’m using one common earth location, a block connector which is in turn grounded to the engine ( one large wire) and I’m using it as a central point for most of the grounds, such as Main ground for the board, fan and ignition relays etc., I was also going to earth the O2 sensor and heater.
Does any one have a view on this, is it wrong, should the main board ground go direct to the engine of battery ?
Kind Regards
Julian
