The "break" might also do you "good"!

If you want to do something creative tonight I'd do the CCM codes maybe. It takes very little time and you will most likely find VATS errors if there are any involved. Instructions here:

Well, if you're connecting your test light in series with the pump test lead, the pumps will not run due to the high resistance imposed by the test light. The light will come on, but there isn't enough current (5+5A) to run the pumps. But, if you set your VOM to read AMPERES and connect the red lead on the pos side of the battery and the black lead to the pump test lead, you should get a reading of 10A which indicates both pumps are running...assuming you have in fact isolated the pump test lead (which sounds like you did).

I recommend too that you install a Battery Tender to the battery to keep it in top shape at all times, regardless of temperature or time between use. And, the battery will thank you as well! (My wife's battery in her 69 C3 is going on 6 years now and it still cranks her 350/350 like new!) I have found the little 800mA unit to be perfectly adequate for battery maintenance.

The grey is for the primary at the tank, and the green/white is for the secondary, this is on 1990, probably the same though. If you jumper the test connector, there should be 12V at both of those wires.

I just changed the primary on mine this week, used a delphi, can get the number if you want it.
