1986 VF500F Honda Interceptor Just bought the bike today. The guy we bought it off of said it needed new spark plug wires. He gave us the wires and also the coils. My husband replaced the spark plugs, wires and coils and we are still not getting any power. My husband went through and checked the fuses on the top of the bike and the ones by the battery. He tested the spark plug wires for continuity. It came back with 4.2 ohms. It looks like everything from the coil on down is good. The bike does turn over, but there isn't any fire. Does anyone have an idea what else he can check? What comes before the coils? The headlight, taillights, turn signals and everything like that does work, except the brake light.

Ok, I finally found a forum that someone had the same problem. This is what it said.... " When I pull the plugs and put it to some bare metal on the frame, there is no spark. Plugs are brand new."
The response he received said " In the back of the bike there are 2 spark boxes. They have a chrome label with colored paint. Unplug and switch them. Then check the same plug you checked before. If there is spark, then you need a CDI/Spark box. It is rare that a wire or coil goes bad on these bikes. It's more common for the spark box to fail."

So, of course we checked that out. And guess what?!?! It sparked! So, now we know that we have to buy a new CDI box.

I am not sure how long the bike did sit. I am thinking it might have been for about a year. He did check the fuel and there is fuel going from the tank to the carb. We have replaced the spark plugs with brand new ones.


There is still no power to the coil and there is no fire to the spark plugs.

Thanks
