2004 v11 cafe sport battery charging

[orangem2]

i have a 2004 V11 cafe sport

Odessey PC545 battery

while bike is running at 1000 rpm idle 12.7- 12.8 volts

when bike is at 2000 rpm and above 13.6 volts

 

Went on a 40 mile ride with one stop... bike started no issue.

 

when i got home i plugged my battery tender harness in and within 60 seconds the green light started flashing telling me battery was at least 90% charged,

 

what voltages should i be reading at the battery at idle and at 2000 rpm and above?

is my voltage regulator reading a bit low?

Charging light NEVER comes on... is that normal?

thnx

Your "battery tender" probably doesn't speak Hawker Odyssey fluently.

A Hawker (EnerSys) approved charger is the ticket.

Otherwise, 1000 rpm is rather low for a V11, IMO. Plus, anything above 2500 rpm or so should see 13.8-14.2 volts.

Stand by for TMI . . .

I read ALL of that already and then some LOL... just 2 questions:

is my regulator rectifier borderline?

should my charging light come on when the bike is NOT running, just the ignition switch to ON?

I believe it should. If I remember correctly, you should be able to check whether the light is working by pulling the light blue wire off the regulator and connecting it to battery minus.

12.8 at Idle is, as far as I know, probably okay.

If it never gets above 13.6V, that's a bit low.

Before you decide that the regulator is not ok, go through the wiring loom and check and clean all of the connections that have even remotely something to do with the charging system.

Anyone got a part number for the bolt used to secure the main ground on the back of the transmission case?

[gstallons]

Uh.... can you look at one nearest to it ? Remove it and measure the length & diameter of the screw and get one . I am not sure if I am looking at the correct fastener in my parts catalog , so go the route of remove and check the bolt dimensions.

So just to follow up...

I reconditioned my PC545 twice.

Standing voltage was within spec, BUT it only put out 80CCA... battery is toast.

Full admission: i keep ALL my bikes on a Deltran Battery Tender, I got 6 years out of this battery.

I checked my main ground on the transmission, and it definitely needed some cleaning and deoxit.

Cleaned the yellow wires plug to the regulator with deoxit also. My regulator has a case ground wire that uses a ground on the frame.

And my charging light does not come on with engine running or not.

Plan is to replace the battery and see what the voltages are at idle and higher, then figure out the charging light... stay tuned!!

Could the knackered PC545 battery be the reason for my lower-than-expected reading at the battery for regulator ou put? like loading it down?

Deciding if a Motobatt is the way to go other than the higher cost PC545 if its more "needy" to keep charged when not riding.

Good work, so far, @orangem2! A few questions at this point:

What year is your V11?

Oil pressure light illuminates KOEO?

What are you using for relays?

[Pressureangle]

Mine had marginal charge voltage for a long time, eventually started coming home discharged and eventually quit while riding. Long story short is my stator-to-regulator wires had poor connections under the gas tank, evidenced by heat browning. I secured the connection and charge voltage went from ~13.2 to 14.5 immediately. 

[gstallons]

I assume you used butt connectors to "hard wire" this connection ?

No, soldered/shrink tubing. No room for wondering. On the Sport I can remove the stator and regulator as one piece.

2004 v11 Cafe Sport

Oil pressure light ON with key ON, engine OFF

GEI 20A/25A relays

 

just ordered picker PC782-1C-12S-R-X replacement relays
