hi, i have an '88 GXL and ever since we had a big storm the gauge cluster is flashing when i start the car. i turn the key and it starts up but i hear a fast clicking sound and the warning lights and shift up light blink for almost a full minute. during this time the volt meter is around 10 or 11 when it usually runs 13-14. i have checked the grounds in the engine bay and was wondering if there are any major ones under the dash i should clean. also the fuses are in good condition. thanks for your help, -Dan

 

thry cleaning the grounds under the dash and also look into a new battery and alternator.

 

battery is new and i just tested the alternator and it checks out.
