PodOne Posted August 3, 2022 Report Share Posted August 3, 2022 Hi all This might be a daft question but I've no past experience to relate to. Completed a new loom for the OD and now need to test all is well. Before I apply any power to activate the solenoid will I cause any damage in doing so given the OD unit will be static?

BlueTR3A-5EKT Posted August 3, 2022 Report Share Posted August 3, 2022 (edited) The overdrive does not need to be turning to test it electrically. The electrical test will prove the two circuits, operation switch, lock out switches on the gearbox, relay and solenoid. Edited August 3, 2022 by BlueTR3A-5EKT Quote Link to post Share on other sites
John Morrison Posted August 3, 2022 Report Share Posted August 3, 2022 remember to have the box in gear. John Quote Link to post Share on other sites
Waldi Posted August 4, 2022 Report Share Posted August 4, 2022 Hi Andy, the solenoid takes some 20A to move, and once it is in the working position (engaged), the current should drop to (from memory) around 0,5A. It would be good to test this; if the current remains high, you need to adjust the solenoid position (lever). Waldi Quote Link to post Share on other sites

stuart Posted August 4, 2022 Report Share Posted August 4, 2022 Also while its engaged check its adjustment on the opposite side to make sure the solenoid is pulling the actuating mechanism in far enough to open the valve inside. (See workshop manual) Stuart. Quote Link to post Share on other sites
PodOne Posted August 4, 2022 Author Report Share Posted August 4, 2022 Thanks all for the advice. The box/OD rebuilt and tested by Pe†e Cox so probably fair to conclude the solenoid/OD adjustments are ok. Just a thought could I not simply wire in a test lamp in place of the solenoid to test the relay, switch and inhibitor operation? Andy Quote Link to post Share on other sites

A test lamp will prove the circuit whereas the solenoid will give you thar reassuring ‘clonk’ as it pulls in. Edited August 4, 2022 by BlueTR3A-5EKT Quote Link to post Share on other sites

ntc Posted August 4, 2022 Report Share Posted August 4, 2022 It will but only if you use a 21 w bulb if it’s bright it’s right do not count on a new ? Quote Link to post Share on other sites
