I was getting ready for work this morning and went to start my 2003 VTX 1800R. It was a little sluggish to start as it sometimes is.
There should be zero sluggish - it should crank over strong and fire off in 2 sec or less.
Do you have meter to do voltage drop test?
While cranking it.
If plug wires were pulled off plugs to prevent starting - how long will it crank strong?
A good 7 sec w/o slowing down is fine.
Meter would show voltage of this attempt to prove battery has the Amp reserve.
I take it you are not there right now to do further tests. Anything below 10.5v -
replace battery.
The next inspection - the bundle in Dust Boot ahead of battery - from ignition switch.
Check the white 4P connection plug - pull it apart - does it look new -
or tan/brown from amp leakage - trying to be a toaster oven.
With key on - charger on -
test bundles along the way from key plugin on out -
to see if loose connection reveals itself.
Reset loose female blade connections to make solid forced fit when plugged back in.
This is huge weak point in most all connection plugs.
Shove a skinny micro blade screw driver down into female port connections of plugs.
Force the female blade connections almost closed.
