Wolfbox shuts down upon starting my Taco

1996 LX 3.4L MT 4x4 Xtra cab.

$104 Wolfbox G930 10'' Rear View Mirror Camera with 5.8GHz WiFi, 4K Dash Cam Front and Rear with WDR, Touch Screen Rearview Mirror Backup Camera, Parking Monitor, Reverse Assist, Includes 64GB Card & GPS

Wolfbox G930 with USB hardwire kit.

Just installed my Wolfbox. It's nice, but when I start the truck, the Wolfbox shuts off. It works fine when the key is in the position just before start. Once the truck is running, I can press the power button at the bottom of the Wolfbox and it turn on and stays on.

I assume the power drawn by the starter somehow convinces the Wolfbox the truck is turned off. Any suggestions?

BTW the red Wolfbox wire is tapped into the cigarette lighter fuse, while the yellow (always on) wire goes directly to the 12V battery with an inline 15AMP fuse.

 

Have you tried just starting the truck regularly without letting the truck sit in a power on engine off key position?

My wolfbox turns on fine except if I have been sitting with the engine off but power on. The wolfbox will turn on and function while I am sitting like that, but turning the key to ignition shuts it off and it doesn't come back on when the engine starts.

Mines just plugged into the cig lighter not hardwired, so I imagine its functionally wired the same as yours.

 

Which circuit is it wired to?

 

Please see my original post:

Errr not until this morning, but it worked fine when I tried this! Ha! Thank you.

Now if I can just figure out why the reverse mode (lines + camera angle) work only intermittently when I put the truck in reverse...

 

Oh man. I must be less awake than I thought Sorry about that.

I was thinking there might be a relay that opens up during starting, but i don't see one on the diagram. I bet the voltage is just sagging enough to make it cut out.

 

No worries @0xDEADBEEF, my coffee has not quite kicked in yet here on the West Coast Yeah I think there is strange thing that happens with voltage going from "engine off but truck power on" to "engine on + truck power on". I can live with that idiosyncrasy, as I've discovered the WF starts up fine when I start the truck from a fully off position (thanks @time623 !).

 

Yeah I've attributed it to some issue losing power and getting power back too quickly. Like it can't turn off fast enough to be ready to turn back on.
afaik all accessories lose power when the starter is on, unless I'm wrong about that.

 

^ been my experience as well. Volts drop to like 9, which will knock out most digital circuitry that operates at 12-15V. You can try a big ol capacitor and a diode if it's that bothersome.
