I am trying to get a 37 WD running I brought
back from way up north. It's possible I need new points and /c but it's a Sunday.
Does anyone know how much voltage I should be
getting from the coil, my gage shows 50 volts. No spark .

if you are talking about the voltage to the plug, you normally get 15000-20000 volts out of the coil. it happens so fast you can not measure it with a volt meter. the 50 volts is abnormal. you cannot jump the plug gap. problem could be coil, but like you say the points can be burnt, shorted or corroded, also condenser can be bad. with coil off tracotr you can touch battery to terminals of the coil, on-off-on-off and see the plug spark, without useing the points.
