Gday Adam .
Great to hear Hot Tip is working 100% now .

You've had quite an introduction to EM's thats for sure .
I haven't had any yet that were as in as a bad a shape as it sounds like Hot Tip was (bent switches etc)

I've found that if you have the manual and schematic you can troubleshoot any EM .
In my experience Williams manual/schematics are the best laid out and have the most info

Cheers
Dave
