I have a frustrating situation with my speed controller. I know how difficult it is diagnose problems remotely but I will try and explain the situation as best I can and then maybe someone could give me some suggestions.
I have a Viper mini 10 Marine Speed controller. I have it in a model submarine so space is tight. The Speed controller is attached to a Hitec micro O5S Single conversion type 4 CH receiver. The power supply is a 6v SLA battery.
The Speed controller works really well most of the time. The little green and red lights flash and the motor runs. I am running a 385 geared motor 2.7 to 1 ratio. Then all of a sudden the speed controller just stops dead. No power or light or anything. The other three chaneels keep working perfectly.
I then have to pull the front section of the Water tight compartment apart and then pull the connections off and reattach them. Then the the speed controller will work perfectly for about 20 minutes and will then do the same thing again! I am running the RC set up through a 5 amp fuse and a small Diode that stops reverse connections.
The reciever is brand new , the Transmitter is brand new (Futaba T4 EXA)
So I don’t believe it is these. The ESC cables run to the other end of the boat to the REC and are twisted around. Also there are some pretty tight turns to be negotiated for the cabling in general. Could there be resistance building up and the ESC just cuts out as a safety? As I said everything else just keeps working.
