Regulator rectifier position

(1/3) > >>

Ken4004:
Many years ago I had a Cb 400 f2 and I bought it on eBay , the previous owner had fitted the updated regulator rectifier on top of the battery cover as per photo attached.

When I owned my Z1000 I fitted an updated regulator rectifier on the frame with one bolt but soon noticed that it got fairly hot when in use so I made a 1/4 thick square of aluminium the same size and mounted the regulator on to it this acted as a very efficient heat sink which kept it nice and cool.
I just wondered what is the preferred way of mounting the regulator/rectifier on the 400 4 so if anyone has any ideas or photos that would be great.

Many thanks regards Ken

Somewhere in a good airflow is best

When I fitted mine, the frame lug which holds the rectifier on was on its last legs, so I fabricated a mounting plate out of an old brass window hinge(!), and mounted the new unit where the original regulator was. The wires were long enough to reach across, and I reckoned it would get the same amount of airflow behind the left cover as the right one. This was in January 2016, and so far so good.

Thanks Mickey

I’ll try and fit it on the original lug which is not a complete lug it’s 3/4 of a lug more like un upside down hook, I’ll try to see if I can find a photo of the original frame to see what the mounting point should look like.

Ken4004:
I think this is the lug for mounting the regulator so as I described
