I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

#5 - If you own a 914 you know the importance of a good ground. As I went through the Subaru harness I counted over 20 grounding points so Suby has a good idea, also.
My question is this. Are there rules that govern grounds? If so, can a layman understand them? Can a ground junction become ineffective if too many grounds converge at one point? Does a ground need to be sized? Should it be the same gauge as the positive circuit it completes? If adding ground points does the material type matter? e.g. brass, steel. As always, TIA, Kent |

As always, TIA, Kent You really can't have too many wires going to a ground point. Because it runs through the chassis, you have a huge wire (i.e. the chassis) to run back to the battery ground cable. The ground wire to the body should be the same gauge as the hot side of the circuit. Brass is a better connector, but steel is fine. For either of them, make sure you have it clean and shiny before you make the connections. Clay |
