Its not the oil pressure sending unit wire. Although its a hot wire, its not hot with the bike off. You'll have to do like Schmidty said and pull fuses one at a time and check for a drop in draw at the battery.

A draw while sitting with the key off is going to be found in a wire that's hot all the time. That's going to be a pos battery cable, stator shorted internally, starter shorted internally or a hot wire to the ignition switch or alarm related. Everything else becomes dormant when the key is turned off....

Check your rectifier wires and I'd remove that battery after charging it 100% and let it sit overnight and check for a static draw. If it drops below 12.6 volts sitting on the bench after 8 hours after being fully charged, then it has an internal issue in the battery.

So are the modern AGM batteries susceptible to shorted cells like the old lead acid types?

if you haven't pulled the battery yet you can put you meter on it and leave it on,,,,, with the bike ignition off you should see no draw on the battery, or very VERY little overnight

Dropped to 12.6v overnight, and running the leads of my ammeter shows no draw with the ignition off ( 9 mA). Probably just replace the battery in the not-too-distant future.

AGM stands for absorbed glass mat. Extremely durable and designed to withstand vibration unlike old style batteries. I've seen one last 9 years but most go 5-6 years. HD has had a rash of them over the last 2 years that have been turds.

Www.BatteryMart.com sells the same AGM battery as Harley, made in the same plant for $99 shipped to your door. I have one in my bike.

I bought my 03 Roadglide used with 1600 mi. on it in November of the same year. In the spring of 04 the batt. was toast. It would not hold a charge. Harley replaced it but not without a fight. In the spring of 05 same thing. This time the new batt. was on me. I purchased a Battery Minder charger after replacing batt. and am still running the same batt. The Battery Minder desulphates battery while charging battery. Sulphation takes place when battery discharges for what ever reason below 100% of open circuit voltage. Check it out BatteryMinder model 12248. PS my buddy has a 2000 Road king with the original batt. He turned me on to this charger/maintainer.:
