1987 Turbo dying while driving
 

My FC Turbo II was running fine the other day, but I took it out for a drive and hit a bump and my gauges dropped to zero and my fan light started blinking and beeping at me. I hit another bump and my gauges jumped back to where they left off and the fan light stopped blinking and the car drove normally. I only made it a short distance before hitting another bump and then it died completely and stalled so I pulled over and towed it home.

I know it's obviously something electrical but I'm not sure what connection is loose. If anyone knows what could cause this I would appreciate it .

Thanks,
Zeke
