Voltage regulator adjustmnet
« on: September 18, 2017, 04:42:42 PM »
1977 CB550K - Stock wiring.

I recently determined my battery was being over charged and based on
the information in the manual I adjusted the voltage regulator and the
problem was easily resolved. My question is, is it typical for a voltage
regulator to go out of spec? The regulator did not appear to a have been
tampered with.

Thx
Steve

Thanks Calj

I took the recommended resistance and voltage reading when troubleshooting and all were within
spec but I think I will go back and re-check.

Steve, posted this in the wrong area to get an answer... copy the thread to the Tech or SOHC/4 bikes area or it is not likely to get much of a response.
email an admin the thread link to this one so they can delete it.

Regulators get old and the procedure is there to correct this issue, so it was an expected thing that may need to be done. So, no it is not a sign of a defect, merely a 40 year old design that has held up surprisingly well.

 If you find in 3 months or a month it is off more than 0.1 of a volt from your currect reading when you have a fresh 9v in your multimeter, then I might want to monitor and possibly replace. 

If you have not scrubbed and cleaned every connector in the last 2 years or since you goth the bike (brass brushes and rifle cleaning bore brush for the female barrel terminals, then you should consider that overdue. 

Write it down in a maintenance log book, if you do not have one start one, as it can show an insurance agent trying to establish value that you maintained the bike and that it has probably has become more reliable.  An accordion envelope or poly envelope with receipts, good idea to scan them on computer as they will often fade to be illegible with time is very useful.  Do not need to total them to keep a tally, especially if the spouse complains of the money you spend on the bike.
This also tells you the last time and mileage you did something.  If you want to be thorough, create an entry and list the parts & # s along with source and price paid w/shipping if ordered and shipped or where locally it was bought. Part numbers are important as ability to find the number later if locally sourced and not using a honda part number is important.
Better to be fastidious in this area, it has its rewards if you ever have a need for those records.

The emgo switches tend to go bad quicker than the oem honda except those at the steering head/neck.  With yours being a 77 you do not have the more problematic switch.  You can use the replacement Emgo switch as I believe it fits the Honda part just like the original.  If your switch has too much drop and you can not clean it to fix your problem.  If you clean the switch be sure to re-lube the contacts correctly to slow or prevent oxidation.  Leaving them dry will accelerate wear.

The voltage at the black wire was within .1 volts.
If I remember correctly the voltage level at 4K was 15.7 don't
remember the others.
