It worked fine, no problems at all, before the winter lay-up but now it will not start up - the ABS light goes on when I turn on the ignition, goes off for about 5 secs when I start the engine then comes back on and stays on. It is supposed to go off when I get to walking speed.
It has got power, its external relay pulls in and the fuses are OK. The sensors all show the same static resistance (about 1k I think).
Before, when it worked, you could hear the pump kick in when you got moving but not now.
Does anyone have any ideas? A schematic circuit or test info would be great.
