i have 78 150 rude and the 1,3,5 bank has fire the 2,4,6 does not have fire and the engine will run what would cause this to do that.

help please

I'd guess power packs..swap them around and see ...

how do u test the power pack or stator

Also check all of the plug connections to the power pack. Look at them real good to make shure a pin is`nt pulled back. Clean them real good with electrical cleaner then coat with petrolium jelly then clean the grounds same. Not a good way for you to test stator but most likly it would`nt fire at all if stator was bad. The power packs, like said, you can swap sides to check.

Will packs from a V4 work on a V6?? I have some for a V4 that we can try instead of buying new ones.

i dont know

no answer

the v6's have a "shift interrupt" switch that cuts power to one bank while shifting, if it gets stuck, you'll lose fire. The switch is in the vicinity of the shift lever under the bottom carb.

spark on one bank of cylinders rules out stator, just leaves powerpack and timer base.

www.shop.evinrude.com click on 'electronic parts catalogue' you can cross reference part numbers.

is there a wire that plugs into this switch because we rebulid the carbs and could have knock it off

ttt

knocking a wire off, would just cause the switch to not function, other words, you'd be shifting a full rpms.

if it's the switch that's causing the problems, it's because it's stuck in the 'on' position, doesn't spring back up after the shifter passes over it. if that makes sense?

but yeah, it's wired to the ignition.

V4 power packs will not work. Switch sides with yours and see if fire changes to other side.

do the 78 model have this shift interrupt on it i looked for it and did not find it.i also which coils over and it work on one.Took two to one. but no power on the other side 2,4,6 side.is it a bad power pack and how do u test it to see if it is bad,and is it also called the neutral safe switch
