Hi all,
I'm just getting ready to swap out my Mercruiser 3.0L TKS carb with a rebuilt Rochester with electric choke. The wiring harness for the TKS is not compatible with the electric choke post, so I will need to rewire. I know I need 12VDC key-on power, but I'm no electrician, so looking for some insight here.
1. Where do I draw power from? Have differing opinions including connecting to AC post from alternator, positive from ignition coil, or just cutting the TKS harness and fitting a new spade connector. What is the best method?
2. Do I need to fuse the wire? If so, what fuze size/wire guage?
3. Ground or no ground?
Thanks for any help in advance. Have already lost nearly a month of our short summer (Northern Canada), can't afford any mistakes or fried components!
