All leds are on

[Ton C5]

I am stuck fixing my IP. all leds are lit, left and right and when i press the motor switch i can hear the relais clicking (motor not connected)
the thermistors are connected.
replaced R21 C11 and C12. (they were black)
i ve got about 3.8 volt going out of TR3 and 2.63 volt at TP4
not sure about TR3 but they are usually good or not working have no spare to replace it

any thoughts ?
thinking about bypassing TR3 with the 5 volts from pin 1. has anybody tried that with succes ?

I think your problem is probably in the control box - look into the op amp and the three transistors - Marty

I switched IP's with an other C5 to exclude wire and CB problems.
so i think i can now safely state that the IP is the problem.
the fact that the relay works, does that mean that the ULA is oke ?

Sadly not - the ula can still give false displays but allow the motor to run as normal - do you have another POD to swap ula chips ? - Be very careful removing them  PS have you checked for dry joints on the connector block ? Marty

[Ton C5]

Yes i ve re-soldered all point of the connector.
but i am a little scared to mess around with my good IP.

any thoughts on bypassing TR3 or is that useless
