Topic: 10K mile, 42 year old regulator and rectifier, what kind of failure risk?

[drj434343]

Looking to take my CB 500 on some longer trips this summer, and am in the process of proactively adjusting or replacing all the consumable parts I can think of prior to the trip, so as to avoid roadside wrenching.

I've come to my original regulator and rectifier, which seem to be working just fine to keep the bike charged.  I'm trying to understand what kind of failure risk there is with these out on the open road.  Should I consider one of the fancy solid state combo units proactively, or run the originals without worry?

If it works don't fix it. Consider a reg/rect an upgrade for when it is needed.

Here's another I think about it.  If the risk is anything but extremely low, I'd replace it now.  The cost of a new unit would be far lower than the cost of getting the bike back to my house from the boonies where I'll be riding.

Should be fine, it is not like it is rubber bits that use it or not it has a shelf life

I think the weakest point on the rectifier is the insulation that breaks down with age. Check your connectors for corrosion and signs of wiring over heating. If all is good don't mess with something that works fine.

Sounds good.  Bike was stored inside during it's life, so I think the 10K miles are more of a factor than 42 years for these parts.  I've inspected the connectors and wiring for heat and breakdown, but all looks good, so I think I'll just clean contacts and run it!
