On these new units, the secondary windings are measuring 5.6 to 5.8K which is close to the GM recommended range of 5.6 to 5.7, but the primary windings are measuring 1.7 ohms - GM recommendation is .5 ohms. I am also a little suspecious of the part no on the replacements; it is 10482928 rather than the numbers Greg quoted above. I am thinking - don't think I will use these replacements. Am I being too cautious?

Another too good to be true? Those are half the cost of AC delco direct from delco.
