Yesterday morning I tried to start the Hyundai and it cranked for like a second (waka waka), but then stop cranking and made a "click click click" sound. I thought it was the battery so I took it out and got it tested... battery is good. Put battery back in and tried again. It made *one* waka, then just click click click.
"The starter must be bad" I thought. Took the starter/solenoid assembly out and got it tested at the auto-shop... starter runs just fine. Came back and installed the assembly back in, turned the key and just "click click click", no waka, let alone a single puff.
At this point I said "Oh crap, Engine must be seized/stuck" and called a mechanic to take a look. Guy comes in and says, the click comes from the solenoid so, solenoid is good. He uses a jumper cable from the battery to the Starter's "connector" and voila..."waka waka puf puf puf broom... brooom", and the car started.
I then checked the battery terminal. Looked good outside but the inside was rusted, right where the starter's cable comes in... sounds like that's it. On my way now to get a new connector. :\
