Electrical voltage fluxes

[Oldtimer79]

Electrical voltage fluxes when reved up on stand causing lights to "twinkle". Normal condition when idling. Meter on battery posts confirms. Honda PCX 125 with 12,000 miles. Engine runs smoothly.

What’s the voltage on the battery when the engine is off?

[Oldtimer79]

Voltage on batt about 12.7 when not running. Then rises normally to about 14v. when reved up.

Take the battery down to any auto parts store and have it load tested… This is different than a voltage test… It’ll tell you whether the battery has a problem storing energy or not…

Thanks, Jge64. I'll do that and get back. The symptom is even present with the trickle charger connected and indicating a fully charged battery.

Hi Jge64:
Took battery to J&P cycle center. They did load test. They told me the battery was about 50% down from new -- but with enough energy to be satisfactory.
I will buy a new battery anyway because it looks to be the original battery which would be 9 years old. Meanwhile . . . back at the ranch . .. now it's working fine ??? Is there any benefit to turning a gel-type battery on its head once in a while? Changing positions maybe helps. ---Thanks for the help.--Oldtimer79

Could be you have cleaned the connections by removing them and replacing. Earth a bit dirty?

9 years for the battery isn’t bad, I think I’d be thinking of replacing it as maintenance too.

Hi Jge64: Got new battery -- great no problems. Now--next day no starter at all?? Troubleshot as best I could. Can't find anything. Starter relay is not activating/ rear brake light operates/ Kill switch should be OK -- nothing would change that. Sidestand switch seems normal although it looks a like major job of pulling left panels to check the connectors. I'm about ready to have Honda dealer pick it up and fix it. Thanks for your help. --Oldtimer79

Does the orange light on the dash turn on and does the fuel pump make a sound?
Don't forget about the red engine stop switch, if you live in the USA.

The kill switch has been glitchy for me in the past. Try and flick it back and forth a few times.

New Kill switch fixed it -- though Honda Dealer fixed it. --- Oldtimer79
