Hey so I’m not for sure if I’m doing this right or not but I have a question about my 98 accord. For some reason randomly the speedometer and tachometer will both drop to zero then bounce around and finally settle to zero, then my radio stops working and windows won’t go up or anything. I replaced the alternator about 6 months ago and just did the test with the battery where you take off the positive and it stayed running, any suggestions on what it could possibly be?
