MS2 3.0 No Spark Single Coil
Posted: Mon Jan 01, 2018 11:53 pm
Hello All,
I am working on my Datsun 240z with an l28et swap.
I have successfully wired everything besides the coil and the dizzy with the coil being my next project.
I have installed the Bip and followed the instructions on DIY's site as follows. (everything else is normal wiring)
Remove the jumper from JS10 to IGN or the center hole of Q16 (if exists)
Jumper IGBTIN to JS10
Jumper IGBTOUT to IGN (V3.0 only)
If you do not have a BIP373 transistor in the Q16 slot, install it.
I am in TS trying to run the spark output test and get no spark.
I have the test setup as follows...
-12 volts to coil from relay with 15 amp fuse
- 36 wire to negative
- stock 240z coil (does use ballast resistor normally but am not using it in this test)
- plug wire on coil to spark plug
-spark plug grounded to chassis
I have tried....
- switching output from JS10 to D14 (still confused on this)
- plugging in my megastim and testing spark (LED lights up with either JS10 or D14)
- checked volts on coil in car when doing test at 2ms intervals (8-9 volts)
Questions I have...
Which output should I have? JS10 or D14?
Should I be using the ballast resistor? I think the 280zx coil does not use a ballast resistor and maybe that is my problem.. I need the 280zx coil?
Why would I be getting low volts on coil during test? This must have to do with resistance?
Should I be getting 12v with key in start when not in test mode?
Sorry if these questions are stupid. I am still a little confused on some of this and want to make sure I am testing things correctly.
Thanks for you help,
Shane
