Got a 25 amp generic Chinese controller..trying to add a cheap thumb controller, no drive.
When I connect the red and black the voltage drops to 2.5v and nothing comes out on the green.
If I short the green from the controller to the red 5v+..it runs ..flat out obviously.
The volt drop worries me..ordered a new thumb throttle..or is the controller faulty.
 
Sounds like the fix is replace the throttle, asking the vendor for a new one free.

Don't take the thing apart yet, till you get a refund or replacement.
