Help with sub electrics please

[roddy.mcaskill@tesco.net]

Hi
Can anyone help me please? I bought a Sub on EBay some months back - a sheerline OHIO. I've only sailed it once but seem to have run into some difficulties. All seem fined when tested on the stand, however I can no longer get the hydroplanes to work. I've tested the servo ok, and the receiver works (although I am confused where it gets its power from, as there is no lead attached to the Battery socket!??). Close to the servo for the planes is a small circuit (which I presume is the autoleveller) but there are no markings on it to identify it - there are 3 leds (yellow, white and green), when the 12V battery is attached to the main terminals of the sub, the yellow and green leds alternate on/off. The White LED remains off. There is a switch (which I presume allows you to set horizontal, but pressing it has little effect. Since taking the sub apart to idenfify the problem I've now run into further problems, where the speed controller, continually alarms 'no signal' but again I can find no problem with the wiring. The motor also now fails to run, although the servos (except the hydroplane) all energies when power is applied, but don't move under control from the handset. The problems are as I see it are twofold - 1)something is wrong with the setup on the speed controller (www.modelcontrollers.co.uk is printed on the controller but this link no longer works), as I have tried a different handset, receiver and crystals all with no change to the problem. 2) something is wrong with the levelling circuits preventing the planes working.

Anyone offer any advice on solving this crisis please?

Try this- Unplug the speed

Try this- Unplug the speed controller from the receiver. Connect a 4.8/6v battery to the receiver battery socket. If everything works (other than the motor ofcourse) then the problem is your speed controller. If everything other than the rear dive planes work, then your autoleveler needs seting up/fixing as well. If nothing works then its your receiver or Tx.

The device you mentioned is

The device you mentioned is an APC- automatic pitch controller, or leveller as they are sometimes known.

The reason the hydrovane servo isn't working, is probably because the APC has lost it's setting somehow.

Where are you based in the UK?

Ahh!
Not exactly round the corner

Ahh!
Not exactly round the corner then- I live in London!

Was going to suggest coming over and giving you a hand, but hope you're not offended if I politely decline.

I have instructions for your leveller if that's any help.

Andy, no offense taken, although

Andy, no offense taken, although if you are ever up this way please feel free to drop in. We have a great view of the subs coming and going from Faslane. If the weather is clear!

Had some success with the model. Seems the crystals (which were relatively new) have packed in! Changing those corrected the radio problems (and 3 of the 4 functions worked again). Except the Hydroplanes! However, in as last attempt to fix (before having to shell out £45 for a new one) I plugged the circuit in whilst holding the switch on the board - success ... this must have performed some form of reset. As for your instructions I would be most interested in a copy. I've learned, press the switch when unit is horizontal -sets the datum. Yellow and Green then switch on (and the servo moves) as appropriate for the direction of correction. Red seems to come on, when horizontal or when radio signal overides sensor. Can you tell me why there is an aerial lead attached to the sensor card? Also, still confused as to where servos are getting voltage. There is a 12V battery for the motor and pump (and the servos obviously ) but as I said earlier the receiver has no seperate 4.8/6V battery attached. So everything is taking power from the 12V battery?
Thansk for everyones help - much appreciated
