Re: Dead battery and TPM
The TPM sensors do not drain themselves dry trying to contact the TPM receiver when the KGT is parked. They have an internal switch that senses when the wheel is rotating, and that's when they communicate with the TPM receiver. Other than the relatively low self-drainage, the TPM sensors in your wheel should hold their charge for a few years at least. My 2007 K1200GT still has the original sensors with original batteries, but it takes a long time for the rear wheel sensor to connect, and sometimes I get an error on the dash until it does. Most of my KGT friends were replacing their sensors after 5 years or so.
I consider it one of two possibilities:
1. Most likely the TPM sensor batteries in the wheels died of old age during the time when the bike sat. The dead battery had nothing to do with it.
2. It is very rare, but the TPM receiver could have failed, or a problem with related wiring, or something like that. I doubt it, but it can happen. My TPM receiver had to be replaced under warranty about a year after I bought the bike.
