Hi all
I removed the electric start and solenoid and primary wires from solenoid with the idea that I would use a smaller battery and kick start the bike I don't seem to have any juice at the coils with the key on now is this normal is there juice there only when the engine is turning over? any pointers would be helpfull Oh bike id old 850 Yam triple.
Thanks Chiz
I am shooting from the hip here but yes with the ignition on the coils should have voltage (Red/White wires).

Not sure how their wired up so could be either way. Also not sure if you are talking of the starter switch solenoid or not. (a pic might help.) Apologies if I`ve missed a post somewhere but what is the prob existing before you pulled the wires? Assuming you have the normal battery charged and tested under load you don`t need to be providing another power source at the starter solenoid as it has nothing to do with power for ignition me thinks. What happens when you just kick her manually with existing electrics on?
Here`s a link that might help clarify where I`m heading. http://www.motorcycleclassics.com/tech-corner/1977-yamaha-xs750-electrical-problems-zbmz12jfzbea.aspx (http://www.motorcycleclassics.com/tech-corner/1977-yamaha-xs750-electrical-problems-zbmz12jfzbea.aspx)
If it is that solenoid you need at least 2 sources of power (One direct from the battery ...thick wires) :drinks:

oK I removed the wiring's to batt to solenoid and the red/white blue/white at solenoid so I could use the kicker and smaller battery. Now I have juice elsewhere with key on but not a red/whites to coils.
