I have been installing 1984 Perkins
low line with the cold start feature in my boat. I have use the old wiring
harness but not the panal, used the custom made panal that was installed in my boat as it was in much better shape than the one that came with the motor
as part of the purchase
. Any way today I was starting to sort out the ignition circuit for the preheat element at the air intake on the manifold and as Perkins
ran two wires (Maybe 10 gauge) to the element and a ground off the other end of the element I was a bit confused (Lucas insanity). I want to fix a seperate push button switch to activate the heater so I was trying to figure out what the two wire deal was. With the intake cover off so I could view the element I was suprised to see that when either one of the wires touched to a positive lead the element started glowing bright red, and after maybe ten seconds I got maybe a three inch flame in the intake. Once the wire was disconnected flame goes out. The first question is is the flame in the chamber normal? The second question is why is Perkins running two hot wires to the element, if the answer is an amperage issue why not one large wire properly sized for the load?
