Ok, so I shot an email off to Tourmaster asking them about the controller and whether it was a pulse or rheostat type controller. The answer I got back wasn't clear, just "it used less power at lower settings". I figured a quick test was in order. I looked at my multi-meter and it doesn't measure amps. Bummer...then it struck me. I have an old 13.8vdc 20A power supply hanging out in the garage that has a built-in ammeter from back in my Ham Radio days. I got it warmed up, took the leads for my electric gear off my bike and hooked them up to the power supply. One click on the Syngergy 2.0 controller with my jacket plugged in yielded a bouncing ammeter. It bounced less the more clicks I went up until it was steady at full power. Hrmm, maybe the meter or power supply is bad? So, I hooked up my slime tire inflater. The inflater drew 2.5 amps steady. Power supply OK, meter OK. It appears that the controller that comes with the Tour Master Synergy 2.0 heated jacket is actually a pulse type controller and not a resistance type. Can someone else confirm this bit of good news? If confirmed, then I won't have to go spend the $$$ on a heat troller to save watts/amps. Also, at full power at 13.8VDC, the jacket was drawing 10amps (un-calibrated meter). The manual says 64.8W (5.4A at 12VDC) and I was expecting 4.7A. Could be the pulse width causing a faulty reading or my ammeter sucks. Either case, is there someone else with this gear that could take some better measurements?
