Ok guys, I really need your expertise now.

This morning the Jeep wouldn't start. No click, no crank.
Remember that my NSS is bypassed and still no start. But I still have reverse lights, it would only start in P and N with the bypass. New NSS is ordered, probably take a couple days. New starter.

What is going on here?
Could the battery be at fault? The Neg/Pos cables?
Grounds are clean, might be bad cables though, not sure about them. Don't look or feel bad.

I'm clueless so I'd really need some good advice.

Starting your jeep requires amperage, not voltge. Is your charging system properly charging the battery? How many CCA's is it tested at? Could be a bad battery.

Think the starter is fine but not 100% sure it gets proper power.

Battery is a Varta and at least 2-3 yrs old, so yes, could be that.
My negative battery clamp was a bit loose so i've replaced that. CCA's not sure..

Pull it out and get it tested at a parts store

Of course you need good power out those two from the battery. A charged battery will rest at 12.7 volts at room temp. Below is a thing on the terminals. If you have one of those funky deals that clamps on the cable, those f up allot. Jumped with jumper cables partially bypasses the connection to the bat...also, the one small (green I think) wire to the starter is the one that when powered tells it to crank.

Battery gasses have a nasty habit of helping a thin, hard crust form on the bat post's and clamps. They can look pretty good, but that micro-thin layer is a surprisingly good insulator. SHINNY! Lead is what you want. I use a pocket knife, (gently), for the insides of the clamps. For the posts I might use one of those post cleaner wire brushes, but still scrape it with a blade. If you have a condition where you have power, (dash lights ect.), then when you hit it power goes out altogether, that's a common result of a layer of oxidization there. Btw, a half *** connection could be expected to get hot during cranking, or while it's trying. Cleaning those is something to do now and then anyway, so it you are having starting problems, you might want to make sure you have bare lead on lead. Might save you some grief!

Terminals are nice and clean, same with clamps. Did that earlier in the thread
Im starting to suspect the battery more and more.

However, the Jeep started this morning. Yesterday we replaced the loose Neg battery clamp. Pos one seems fine and not loose.
We'll see during the day..

Well, loose doesn't get it. Over the years at one point or another I've grabbed about anything to make it fit tight. IIRC I never dried a "freedom fry" . Usually a twig or a folded part if a "beverage" can can get you home.
Really do do much with a Renix jeep. (or anything) a $5 digital meter is a pretty good investment. (Harbor Fright).

Agreeing with Freedgr, if there is an issue with power available, (likely?), the headlights will not be bright while you are asking it to start. Another thing without a meeter you can get a sense of running voltage by the speed of the blinker.

Anyway if you have a battery that won't hold a charge, loose connections, and no meter...cool that it starts at all!

This is faster and easier. Best $3 you'll spend on tools.

Can someone explain exactly how someone jumps the starter?
Anyone have a photo?
The key is in "start", and you jump it, and the engine cranks?

It seems sawww did stuff out of order. The first thing I would have done is the clean the terminals and tighten the battery cables.


Quick Reply: Battery has power, but when I turn the key nothing happens...
