Hey old boy! Just spent a hour going through your whole thread.
I'm actually a forklift mechanic, and i work for Toyota (we own Raymond) so i work on busted up buckets of **** like that prime mover nearly daily. Have you got it sorted out yet? Or are you not going to bother due to getting the Maxjax?
If you still want to fix it, or if its not fixed yet, PM me, I'll try and go through some information/diagnostics on it with you... key word there is TRY.... I should be able to find a workshop manual for one at work somewhere, but those prime movers are ancient, i used to work on them when i was a apprentice ( over 10 years ago) but now, at least here in Sydney, we have none left in our fleet!! I haven't worked on a prime mover in years!
50% of the time, problems on electric forklifts end up being battery problems, if its flat, or old, and has dead cells, they will throw every code under the sun into a forklift.
The first thing id be doing is load testing that battery.
Oh, we were talking about your garage weren't we?
Looking forward to the updates on the shop, I like the original owners concept, that would be the dream, buy a warehouse space, convert upstairs to living quarters, and have a mad workshop underneath, I asked my wife what she thought of the idea and she laughed at me, said "you want to live there alone?" hmmm its sounding better and better!
