Greetings,

I have a Honda CBR 600 F4 (1999) in which I have gone through two voltage
regulators now, due to their poorly designed heatsink (or lack thereof).
These babies cost $80-130 depending upon where one decides to buy them and
even then this is typically a "used" price.

After the second one fried (just recently), I decided to give a go at
reverse engineering the voltage regulator/rectifier, though with no avail --
as they have the circuitry conveniently (to them) packed in that annoying
anti-reverse engineering epoxy. So, breaking this epoxy results in breaking
the circuitry of course, thus leaving me with shattered pieces of components
and epoxy.

Honda must know at this point (consider my particular motorcycles age and
given many others experience this known issue) their part is faulty, albeit,
it's obviously good profit margin for them to keep their customers having to
purchase many of these through their motorcycles lifetime. I personally am
fed up with it and would love to obtain a schematic of a voltage regulator
replacement. It is a 5 pin based rectifier, with a positive, negative and
three alternator fields. I'm uncertain as to the AC voltage output of the
fields and the current/amperage requirement for the positive/negative
charging side. Though I'm hopeful there may just be an electronics expert
on the NG's that may have made one for themselves. I'm told the "superior"
Suzuki 5 wire rectifiers would work, however; I'd hate to invest in one
which will be once again, $80-130, only for IT to burn out just months later
as well. I've checked my charging system and the fields did show an AC
voltage of what the manual calls for (I'm just not in a position at the
moment to look up those acceptable field voltages). Resistance in the
charging lines are minimal/within tolerance. And the battery has been
fresh/new with each rectifier replacement (to ensure no amperage overloading
due to a bad cell in the battery, etc.).

Any assistance is GREATLY appreciated.
