Note that external solonoids don't help hot slow cranking. You need a 1000 CA battery and heavy cables like 1 gauge
I have 1000 CA battery.... all new parts... still turning over slow.. not just when hot I notice too... I may replace the battery just to be sure.... ill put it in my truck as the 2nd battery and get the bird a new one... I took it out today and boy its got some power!! yeah!! been a long project but so worth it!!!
as a side note.. can anyone see a reason their would be a ground wire on the I terminal?? of a remote solenoid?? the vettes up and running but it had a ground wire from the body to the I terminal I didn't hook back up.... seemed odd since the solenoid was grounded to the body.
