Can anyone please tell me the location of the Air Flow Sensor for the Battery Box? Manual says, before the blower fan. From under the truck, I can barely see the power plug for the Blower but don't see any other electrical plugs. Am I looking in the wrong place? Kevin

Hi, Kevin-- As you probably know, the battery box is sealed: no air flows in or out. The blower inside the box circulates inside air through a cooling condenser and around the batteries to cool the batteries, chiefly while charging. The air flow sensor simply checks that the blower is working. The wires for all the sensors -- battery voltages and temperatures, plus the air flow sensor -- exit the box independently of the wires that power the blower. The blower requires three wires -- 12V+, chassis ground and a TTL-level Pulse Width Modulated signal to control the speed of the blower. To get to the air flow sensor, I'm pretty sure you have to open the box. --Gil > On Jul 15, 2018, at 12:48 PM, bjnkm--- via S10-EV <[email removed]> wrote:

The sensor is located in a small black tube around the fan. Look for a 2
position connector, grey, with yellow and orange wires going to it. Attached photo has it highlighted. Resending this message to comply with
the 300kb size limit. ​ On Sun, Jul 15, 2018 at 6:31 PM, Gil Dawson <[email removed]> wrote: > Hi, Kevin--

Thanks for the reply!
I saw that and wish it was that easy. What I believe you have in that photo is actually the outside air valve. It's purpose is to allow a small amount of outside air into the box to purge any possible gases from the battery box. On top of the battery box are discs, about 2" in diameter that act like one way air valves to release any internal pressure. I'm not sure when it's activated. Maybe during charging?
As for my issue, after doing more testing with the Tech 2, I believe my problem may be the Heating Thermal Control Module, (HTCM). That little box under the driver's seat. Now I need to find one.

Hi Kevin, Send me a PN and a picture of the module you need and I will see if I have one in my parts collections. Steve
