I'm a newbie Bonnie owner and trying to install the boyer ignition. I disconnected all the wires from the coils, condensers and rectifier. Tying to wire the Boyer Mark IV (I think, the case isn't in front of me) box to the coils and rectifier. Can anyone tell me what color of wire the ignition wire from the Boyer connects to? Also, what wires (color?) need to be connected to the rectifier? Struggling with something that should be easy. Thanks all!

Rock,

I am struggling to understand exactly what you are trying to wire to what. Would it be too much trouble for you to take a look at your Boyer and mention what model it is and also take a look at your bike and provide information on the year and model or do you expect an answer that provides encyclopedic information about all Boyer models and all Triumph Bonnevilles supplied to you in a convenient matrix? Did you know that the Boyer website includes detailed instructions on how to install their units. Would you like me to look that up for you and provide a link?

Respectfully,
Henry

It is a Mark IV Boyer ignition system. I'm trying to install it in a 78 bonnie. I'm not going to make it sound like I know much about the wiring on these things. I'm more of a mechanical guy than electrical. Anyway, I have the stator plate installed and wired. I'm trying to hook up the black box. I unhooked the wires to the coils, condensers and rectifier (wish I didn't unhook them now). I tossed the condensers and trying to wire the rest. I'm not sure what gets connected to the rectifier if anything (what color are the wires and where do they go?). The rectifier is still needed correct?

Oh, and I have the Boyer directions and a wiring diagram for my Bonnie. The wiring diagram I have doesn't show a good representation of where the wires actually connect to the rectifier.

None of the wires connect to your rectifier.

The unit is powered by switched on/off DC.

First thing: are you negative or positive ground?

Rock,

I have reviewed the Boyer Mark IV instruction sheet and found the schematic impossible to read and of little use. Overall, the sheet is poorly designed. I have sent an e-mail to Boyer asking them about their poor documentation. I'll post their response here if they send one.

It is a positive ground. The bike is 100% stock. I think I know where the wires for the Boyer go, I'm just not sure what to keep on the bonnie ignition. I know that the condensers are not needed. What about the rectifier? Is it still necessary? I think Boyer's directions are poorly written.

The rectifier is not part of the ignition system. It is a part of the charging system. Bob

I got it hooked up now and actually got it to fire off and stay running for about 15 seconds. There is a constant clicking sound coming from the capacitor. I'm guessing I have a two wires crossed at some point. I'm almost certain I have the two stator plate wires hooked up correctly and the black and red wires coming from the Boyer box. I hooked the white wire from the Boyer box to the white/yellow wire on the bonnie. I'm not sure I hooked all the wires up on the rectifier the right way. I attached a pic how I wired the rectifier. I can't seem to get it started again. My plugs are new, but my plug wires are original from 1978. Could my plug wires be the problem? Do I have something wired wrong on the rectifier? Or does the stator plate need to be advanced one way or another. I appreciate the help!!!

I have tested the current and have plenty of juice coming from the power and throughout the system.

I also switched from 12V coils to 6V if that matters.
