79 Alternator+rectifier+regulator

Postby rpsanders » Sat Jul 06, 2013 3:52 pm



After not being able to start my Rosie halfway through a ride last week I decided it would be a good idea to connect those dangling wires by my battery. there were two of the three yellow's coming out of the alternator which were not connected. i figure these were why the battery wasn't recharging. Now, after connecting the two yellows and jumping the bike i let it run for ten minutes and the battery had enough juice to start on its own. sounds like a happy ending right? Maybe. My question is, should the rectifier be getting hot enough to scorch the two yellow wires in the first place? i mean this sucker got hot fast! and the insulation on the wires were black from heat. remarks?

there is also a capacitor below the rectifier with a blue on yellow and a yellow on blue which are also disconnected. Do these have anything to do with the recharging system? or are they a part of the old condensers and points ignition system ( Rosie got upgraded to electronic before I bought her)

Have at it!

according to my Clymer manual I was wrong about capacitor. Its the condenser case with the multi colored wires. I still can't explain the heat off the regulator. Who uses the more compact regular/rectifier from newer Honda models?

Scorching heat from the regulator is normal. The stator puts out full power at all times, and the regulator shunts to ground what is not needed to run the bike and charge the battery - converting it into heat in the process.

Do a search here for "three yellow wires" and you'll see a lot of information on this whole system and its problems.

I never tested my 78, but the combined R/R module on my 84 would hit 165* in 10 minutes.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
