Electrical issue

[Abbert55]

Hello everyone, I'm new to this site and also to my first GL1500. We purchased it four days ago and it ran fine. I went to start it and found I have no power to the start circuit.
Here is the scoop. I'm very mechanically inclined, the bike is a 91 SE and has a Roadsmith trike kit installed. I've checked the fuses I could find, and all are good. I found a 65A fuseable link under the seat and it has no power as well. I have ACC power. As I said, I'm new to this machine and layout. If you could suggest anything else I might check, Please PM me and I'll give you my phone number.

Thanks for any help you may be able to give.

P.S. I do not have a shop manual as yet, so basically playing blind!

65A fuse is for reverse system and connected to the negative terminal of the battery.
Here is a simple diagram of the starter system for your bike.

Many thanks Erdeniz! Much appreciated. I'll start checking for problems with the diagrams.
