[jakedaawg]

Hello, I need the following specs for a '92 yamaha twin cylinder that is in a little boston whaler. I believe this is the 650 twin cylinder J650c. I dont really want to buy a manual as I doubt it is worth fixing unless inexpensive. Any help will be appreciated.

stator output specs (peak voltage)
stator resistance
trigger coil output
trigger coil resistance
ign coil resistance
