Jensen A528T stress control problem

[TreeTomass]

Hi, having bit of a nightmare with stress control on me chipper. Trying to get it to work. New sensor, new valve and solenoid fitted. When I go to set the control with the buttons on the control box H7 doesn't light up or flash when setting high revs. H6 does when setting lower revs.

Does this mean I need a new circuit board?

Starting to do my head in! Thought it'll be easy fix, sensor and valve/solenoid was buggered so sorted them but still not sorted...

Cheers.

hi mate your probably better speaking to the dealers so you dont spend more cash or damage your machine good luck:thumbup1:

Cheers, yeah I've been talking to an engineer at redwood, he took a while getting back to me, just thought it worth asking here too, incase anyone had a similar problem.

I know this was a while ago but I have the same problem and would be really interested to know if you needed to put a new stress box on or if it was something else. TIA Thomas

Why not give Alan or Shaun at Beaverplant a ring..?

Not a bad idea, thanks Jase!
