I'm pretty sure it's the battery, but this is what confuses me.
For the last 6 months it wouldn't crank at first, just click. So I would always use my jump starter portable thingy. it would start and run, and even start after running for 1/2 hour or so. But then it was dead 2-3 weeks later. Then it got harder to start with the jumper "thingy" - just clicking, but after jiggling the jumper clamps a few times it would start up just fine. So I figured it was just being picky and not making good contact easily.
Now I have a brand new jump starter "thingy." It has an indicator that shows a blinking engine icon when off and hooked up properly. And it is supposed to stop blinking and go solid when turned on and ready to start. I can't get it to go solid. And I only get a click still. Lights work, but there is no difference in brightness when I turn jump starter on or off.
I thought it may have something to do with a super bad battery interfering with the staring circuit or other problem with having a bad battery. The battery terminals and connection look clean and solid. And I can't buy a new battery until Monday - and of course I have stuff to mow this weekend.
And suggestions please?
