Well, on July 8th I shipped my Fuel Gauge, Fuel Bridge and VW Fuel Sender off to AutoMeter for inspection and repair. July 17th UPS dropped a box off at my front door - it was from AutoMeter. No emails or phone calls about my stuff in between those two dates...and no information about what, if anything, that they did to my stuff while they had it. I had figured it was sitting on someone's ToDo pile at AutoMeter.
The tech I had been emailing at AutoMeter didn't even know it had arrived and been returned either - it never crossed HIS desk. He did some digging at his end and found out that another tech had repaired my faulty fuel gauge (for free!) and calibrated the system (no, they didn't). In my bench testing, I discovered that while the gauge WAS fixed, the system still didn't calibrate well. After 3 more attempts, I finally got the gauge calibrated reasonably well at F, 3/4 & 1/2 tank readings. Below 1/2, things get out of whack quickly. WTF...isn't this the whole point of the customizable Fuel Bridge?!? Sigh...I give up. I'll just follow the old Minnesota Winter saying "a half a tank is an empty tank" and fill up frequently.
FYI, the Up/Down buttons on the Fuel Bridge adjust the resistance in approximately 10 ohm increments. But trying to calibrate the gauge for 1/4 tank was impossible. 1 click UP would take the gauge to almost 1/2 tank and 1 click DOWN would take the gauge to almost E. sigh...
