Rectifier

The new rectifier is warm/hot to the touch after running for a couple of minutes--what is normal? I didn't take it out, as I didn't want to blow it up again.

So it looks like a little interneting I did after previous post leads me to believe these things run hot (140-170 degrees), and all the low wattage things I've done actually contribute to the heat generation, since they're not drawing the excess current themselves. Looks like a MOSFET unit rather than a heat shunting unit would solve that problem. Is the internal rectifier in the alternator swap also a heat shunt unit, or can it be changed to a MOSFET type?

I wouldn’t worry about the 40 amp unit. I haven’t heard of rectifier failures on these units. The failures tend to be a cracked housing, and of those, a majority in the UK, and one or two in North America.
