Below is a link to a PDF file for the 12N (85-89) VMAX Wiring diagrams. About 1.6 meg in size.
http://www.vmaxforum.net/local_links.php?action=jump&catid=2&id=67
This has been redrawn from Yamaha's schematics in a format that I hope you will find easier to follow.
I put it in this forum to get some opinions on it cause it seems like the most viewed forum here.
The first page in the PDF is the complete wiring schematic showing all the connectors.
The second page is the same schematic electrically, but without the connectors shown. This makes it much easier to lay out the wires and not have to route them all over.
The third page shows the starting circuits in three configurations. Only the components involved in each configuration is shown, so as to simplify the circuit.
A couple of the obvious errors (IMO) have been corrected on these. 1st is the coil supply wire colors & 2nd is the pick up coil wiring/colors.
I am looking for some feed back from you guys to see if this format would be helpful/used by you. I have done all the Ventures in the same format and it is used a lot.
One of the little quirks on the schematic is the use of PUSH/PULL/FREE designation on some of the switch diagrams. FREE means as the switch position when there is no pressure on switch plunger/actuator. PULL relates to the rear brake switch only, when brake is depressed, the switch plunger is pulled out. PUSH relates to the two front levers, when lever is pulled in, the switch plunger is free in housing. Its is pushed when lever is at rest. Similar with horn & start switches.
I need to know if there are any errors that anyone can find.
To carry on with this I will need some high quality scans of the other model year variations that exist.
As most of you know I am a Venture owner, so my interpretation of a VMax schematic may be slightly off. But I do have about 15 years engineering background as a signal system designer for railroads, so I do have some training to do this.
These PDF's can be taken to an office supply store like Kinkos or Staples and they can print an 11" x 17" copy for a couple of dollars. A lot easier to read than what is in the manuals.
