The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Ayuh,... It won't be model specfic,... But pinned to the top of the Electrical forum is a generic diagram...
You'll be able to figure it out from that...
You also might try contacting Glastron directly and they should be able to get you one.
I needed some information and sent them an email and in about 3 days or so they sent me a pdf of my boats owners manual.
Good Luck
