My gun does not have any response - Troubleshoots

Does it make a Clicking sound?

Issue: Dead Battery
Fix: Try a fresh battery. If no new battery resolves issue, possible internal issue.

Issue: Motor height too high
Fix: motor height should be adjusted.

Issue: Locked Gearbox
Fix: Remove motor plate and motor from gun. Using a small pick, pull the Anti-Reversal latch. If that does not solve issue, most likely a jammed gear or piston.

Issue: Dead Spot on Motor
Fix: Remove motor from gun and spin it by hand to a new spot. Connect to gun outside of the grip and fire the gun. Issue will present itself.

Issue: MOSFET issue (depends on Brand and Model)
Fix: Gearbox has to be taken apart to see any physical damage. If unit has a programming app, connect to that and view error codes.

Issue: Bad battery connection
Fix: Common on tamiya plugs. Internal pins on plug might not be making contact even when the plug is clicked in place. Wiggle wires to see if a dead spot can be resolved.

Issue: Broken trigger contacts/Wires
Fix: Open gearbox and inspect contacts and wire harness. Contact points with too much buildup and lead to no response or the tabs are broken off. Pinched or sheared wires also cause same issues.
