550F charge issue?
Oddjob:
Doesn't appear so Steve. Even today they are still making non mosfet Reg/Res, my CB1300 is non mosfet and that's a genuine part from Honda. Loads have failed on the 1300, I've been lucky and mines just fine but I have a spare just in case.
Sesman:
That’s very interesting. When I finished Uni, IGBT was coming on strong in power applications and I simply took it for granted they would usurp p/n MOSFET Clearly still a role MOSFET for low power applications.
Speaking of reg/rec failures my old 800VFR had an appetite for them. I always carried a spare on foreign trips until I learned a Yamaha variant was more reliable.
Bryanj:
Whats wrong with the original two unit system that is more forgiving, rectifiers only seem to fail if you break a wire off or hit it with a big hammer whilst regulator only needs good, clean connections
Sesman:
Probably not a lot. My 46year old units work just fine, but when they break I’ll go for the solid state option, unless somebody gifts me an original replacement. Out of pure interest , do the sparks on this forum believe the semiconductor option of field control offers any benefits over the elec/mech original solution?
Laverdaroo:
Just aquick show and taell tale related to Reg Rec's. My model VFR800 is reknowed for blowing them as per what Phil stated ablout his VFR. Mine however is the original unit and going strong after 21 years, must be a batch that was crap as never had a problem with it on mine. Must be the lucl of the draw¬!
