Good morning, thank you for this wonderful source of relevant knowledge everyone provides here.

5. StarCraft currently not finding motor (screens replaced but motor is not setup as port)
6. StarCraft Gauges (currently non-functional)
I have read a few different forums on Battery Load testing, Alternator input testing (red and purple wires from small clip), Alternator output testing (Alternator output) and Fusible Link Lead testing. With the resources already discussed on this form, its my understanding the Alternator is bad but would like confirmation from the community that the troubleshooting performed was correct.
1. Battery load test, proved to be successful as expected with a brand new fully charged battery.
a. Starting battery is brand new 1000CCA Interstate flooded battery.
2. Tested red and purple Alternator input wires from small clip to ground, with engine running. (Clip was removed prior starting the motor )
a. 12.76v from both leads.
3. Tested Alternator output (directly on Alternator)
a. 12.64v
4. Tested from end of fusible link lead connection point
a. 12.56v
This connection point where power cable comes in is a bit corroded and will be cleaned once the boat is out of the water.
From the above steps, it seems input is working as expected (red/purple clip leads). Alternator is probably shot and I have a used OEM alternator that came off a parts motor. Please confirm the troubleshooting steps preformed above and I'll plan on sending the used alternator to a repair shop to make it perfect prior installing.
Another question, please let me know if a new thread should be started on this. Is there anyone in Long Island, NY that can be recommended to reconfigure my ECM to work with my SmartCraft gauges or is Vessel View or some other tool worth the money I could purchase to do this and other diagnostics myself?
Thank you all in advance for your input!
Brian
