Pretty much any diode will do. If you get it backwards, the saving grace i s the start solenoid is looking for 12 volts. Of course, the solenoid must be grounded. Most mistakes are the ground is left off the solenoid when putting on the d iode. Another problem is guys don=92t insulate the anode side of the diode and it shorts. The Rotax manual doesn't comment on the diode. But it is an accepted pract ice to extend the life of the contacts in the starter solenoid. The Europa Electrical Chapter 25 advises to use an IN5404 but any will do. IN5404[cid:image001.png@01D75B0E.9AC39E20] silicone diode is shown above. Anode or plus side is on the starter switch tab and the cathode or negative goes to the ground bolt holding on the sta rter solenoid. I use at least a #18 or 16 wire from the solenoid fastening bolt to the main firewall ground.

Look at the diagram, I misspoke. The cathode side on a solenoid spa de contact and the anode or positive goes to the ground. It=92s getting late and the mind is a terrible thing. Follow the pictures in the Bob Knuckles book or the Europa Electrical Diagr am.
