I've got a '93 940 with the Yazaki instrument panel. I'm in the process of adding the "Low Coolant" circuit that the 960s had, as described in the 700/900 FAQ. Everything seems straightforward, but when testing the new light (lamp position 8 from passenger side, icon of an engine melting down), I couldn't get it to come on. I tried directly grounding the appropriate trace from the lamp, and it still would not come on. Diving deeper, I couldn't find battery voltage on the appropriate side of the lamp socket. Moving backward along the circuit trace, I find the next lamp, the 'ABS' light, also has no voltage. After this point the circuit trace runs under a plastic clip, and on to the 'Parking Brake' light, which does have voltage and does light. Seems to me I have a break in the cheesy printed circuit. I jumpered from the 'Park' lamp +12V side to the new lamp and both the new lamp and the 'ABS' lamp then lit.
I just want to verify for sure that the ABS warning light is supposed to come on at startup with the other assorted lamps, and then go off. If so, I guess I'll be installing a jumper here. Good thing I took on this project, or I'd have never known my ABS warning light was AWOL.
