1st Gen Venture Starting Circuit schematics

Attached are redrawn schematics of the starting circuits for the 1st Gen's.

I thought these might help people that have cranking & starting issues.

There is a narrative above each circuit detailing operation. This text assumes a charged battery and intact fuses.

There are three views of each circuit.

Left side shows circuit in normal condition, key off, side stand down, transmission in neutral.

Center view shows circuit with key on, transmission in neutral. clutch and side stand switches not shown as they are irrelevant in this configuration. All switches and relays shown in position to energize starting motor.

RIght view shows key on, transmission in gear, side stand up and cluth pulled in. Neutral switch not shown as it is irrelevant in this configuration. All switches and relays shown in position to energize starting motor.

Also, the side stand relay and Emergency stop sensor are shown. Neither of these affect the cranking circuit but will shut down the Ignitor unit. Actually, the bike will start and run with either of these pulled out.

84-85 one is almost identical to 86-93 version. Only difference is positive wire at starting solenoid coil.

Getting an error message on the 86-93 stuff.

working fine for me. BTW nice job. Oh yeh according to my 1988-89 shop manual XVZ13DU and XVZ13DW are pretty much the same. It seems the U =1988 and the W=1989.

Ironically The cover say's 1988-89 XVZ13DU and XVZ13DW, while the material inside refers to XVZ13S / DS which is actually a 1986
