Timing light hook up

[Yahow lam]

Hi, can someone show me how to hook up timing light on 1987 930 turbo correctly please.

I tried, nothing happen, no light flashing.

Thanks,
Yahow

Depends on the timing light. Old skool inductive light would have a positive clip to battery positive, ground clip to the engine block, and the clamp around the #1 ignition lead.

Hi Flightlead404,

yes, mine is an old school inductive light, I did that, only difference on my hook up was attached positive clip to one of the 3 fuses at engine bay fuse box to get 12V instead of directly from the front battery, is this an OK way too?

Thank you,
Yahow

Yes its fine but you can always put a meter on them to verify voltage.

Hi Flightlead404,

Verified the voltage and didn't get 12V, wiggled the clips around showed 12v and the timing light came alive! Now I know my timing is set correct at 26* BTDC @4000rpm.

Thank you so much for your help!
