Thanks for your article Chris.
On the Ingrams unit there is just enough clearance, once the tails are bent at right anglesto mount the unit.I soldered 3 wires to these tails , with heat shrink tubing. I then soldered connecters to each wire and installed them to a three wire plastic connector. If I need to remove the unit it is easy to uncouple the connector.
After writing my message I took my bike back to the Auto Electrician and he assured me that my connections were correct now. However I have not replaced the plastic cover over the units as I am keeping a watchful eye on everything. The plates do not get hot like they did before, only warm. I will keep monitoring the rectifier and if I have any more trouble I will extract 2 diodes from my old board and do what you have done.
If you look up google and enter "Ingram 9692" there is an article on the RE55 and 9692...
