Rectifier advice please

Rectifier advice please

Post  Harty210 on Sun May 19, 2013 10:15 pm

Further to my last post about the magneto I have a query about the rectifier on my falcon 74, looking at the rectifier, which looks fairly old so I assume it could be original, it has only 2 wires coming off it. I understand that it earths through the mountings and from the wiring diagram the 2wires connect to one side of it (magneto and main switch ), and the other side goes to the ammeter. I cannot see any obvious markings on the rectifier so does it matter which way round it is wired or are the 2 wires on the rectifier ac and dc specific and if so how do I tell which is which?
Also should the wire from the magneto be more than 5amp rating or is this man enough?

Regards
Dave

Hello Dave. My F74 wiring diagram shows Rectifier "casing must be insulated", so no earth thru mountings. I would suggest replacement with a decent modern unit from Paul Goff. This would show which way round to wire it. Pretty sure it has to be wired only one way, ac in & to main switch for direct lighting, DC out for battery charging & lights.

My Falcon 70 uses a remanufactured version of the original rectifier, and was a straight swap in terms of mounting points and electrical connections. I'm trying to recall where I bought it from. It works well, with no voltage 'leak back'.

It had to be insulated from its housing, and I found that the plastic screws and nuts used for fixing number plates to cars / bikes were just the right size - both width and length.
