Good day folks. I a new owner of a 90 Wrangler, 4.2L. Went out to start it and the battery appeared dead. I jumped it and it started right up. Upon shutting it down, I noticed a faint glow from the "brake" and seatbelt lights. They remained dimly lit even after the key was removed. Also, it won't resart unless I jump it. As soon as the cables go on, it starts right up. Is there possibly an issue with a faulty or misadjusted ignition switch? At times I noticed, while driving, that the ammeter jumps around until it rap on the dash. Please help.
