Bought a1986 interstate with 5700 miles and it's been great until a few days ago. Rode couple of miles to store and when leaving it just clicked at starter solenoid. After a few minutes it started. Same thing a couple days ago but got a push start to get home. Ordered a new solenoid which just came in today. But while bored yesterday I noticed the electrical connector was badly corroded and burnt so I decided to bypass the connector and hardwire the wires. Unfortunately all the wires are yellow and I think I may have crossed to of them up. Anyway put new solenoid on today and same issues. Power to both sides of solenoid and also to starter but still just clicks. Any advice??
