anyone have specs for primary and secondary coil - black bosch on 89 525i

[RonnieB]

trying to ohm out my coil as a possible culprit for hard cold start , anyone have specifications?

[Ross]

primary 500ohms +/- 10%
secondary 6k ohms =/- 10%

actually that is what I found in Bently and that is in error. I contacted Bosch directly and they told me that the primary is .5 Ohms , not 500 . Saved me from buying a coil!
