Question about 1997 Honda VF 750 C Magna
95 honda magna, batery swollen starter switch dosent work so owner has 2 wires on starter relay to push button switch , wires (red,black) have honda connectors on them on relay side but i dont know what they originaly were connected to , no power to low beam,tail lamp,blinkers. brake lights work an high beam but if u press starter switch high beams go out till u let off switch, is there a power source that controlls these non working components, or what to look for.
First replace the battery.
Then diagnose electrical problem.
The starter wires originally went to starter switch through a plug in the headlight. You need a wiring diagram.
Get a Chilton or equivalent manual for the bike.

I have a 98 VF2 750C Magna with a similiar problem as stated above. The starter switch is a quad pole switch which runs your accessories with the key on and also starts the bike. With some care take the switch assy. apart and the head lamp assy. Find the wire harness connecting the switch to the head lamp by following it down the trunk of the steering column. Disconnect and clean any corrosion (use baking soda and water with a small brass or steel brush) blow dry with compressed air. Check with multimeter between the contacts on the switch and the associated pins on the plug (easy enough they are color coded). Check each contact between pins and then to ground by touching a solid metal object with one lead of multimeter. All the wires should have continuity to each pin if not you have an open in the wire harness between the switch and headlamp plug. The only wire that should check to ground is the Blue/white wire (ground wire). If any other wires check to ground you have a short to ground replace switch assy and harness (57.00 @ Honda Direct). Out side of these measures you can check between the forward to contacts on the switch and the associated pin in the headlamp while depressing the switch. If you have no continuity as I do then the internals of the switch are bad so replace switch assy. There is a new switch assy. available at Honda direct that replaces the old type found in your bike.
Hope this helps.
The problem is not in your CDI, Solenoid or Battery most likely since you can short the solenoid as seen by the switch you have installed and the bike starts and runs.
