Help - 2013 z1 dies. Radio works. Won't start

[IDBoating]

You're going to have to trace along, starting from the battery and working toward (at least) the ignition switch that you said had no power on it. So, for example, starting from the battery, you'd go to the battery switch if there is one on that battery. Do you have power on the downstream side of the switch? Great. Next, go to the circuit breaker you photographed. Power on both sides? Great. And so on.

There will be a nice big red power cable coming into the underdash area. Confirm you have power on that when the battery switch(es) are on. The ignition switch will likely get its power from the busbar to which that big red cable connects. Somewhere along here you'll find that you have power on one side, but not the other, of "something"... and that's where you'll begin troubleshooting.

Power, as used above, means +12VDC from the battery without the engine running.

Report back!

So we tried to star by bypassing that broken piece. That didn't work. Still nothing.

Tested starter, that has power.

4 cables going to ignition switch, none of them have power.

[IDBoating]

Err... did you measure both sides of the circuit breaker (the "broken piece")? Does either one have voltage? The starter current isn't going to be routed through an 80 amp breaker, so the fact that the starter has power doesn't tell you whether that breaker is working.

[dmbisbest]

No. Nothing is coming from that breaker

[ATTACH]37716[/ATTACH]Circuit breaker by the battery looks cracked. Is that how it should be?

that circuit breaker comes from the ACR and its only for charging , has nothing to do with starting, you ignition wire is a low amp wire , you need to see where it gets its power from , I will go out side now and see where mine comes from , stand by
Hot wire is the red wire on your ignition switch

True, but as I said there is a large gauge red wire coming into the underdash area that supplies power to things like that smaller ignition switch wire. That's why I said "There will be a nice big red power cable coming into the underdash area. Confirm you have power on that when the battery switch(es) are on."

As for the breaker, at least on my boat the battery isolator in my factory two-battery does not connect through that breaker to either battery. I haven't traced it out in a couple of years, but IIRC that breaker is a sort of "last failsafe" limiting current allowed to flow to the house systems on the boat. Again IIRC, heavy gauge red cable goes from the battery's positive terminal, then to that breaker, and then forward to the circuit breaker box and busbars under the dash. If a short develops along the way that the breaker box doesn't interrupt, this standalone breaker near the battery saves your wiring.

If I get a chance I will trace my boat again and report back.

These two breakers in the back of the boat are only to protect the ACR to the batterys , yes a big red wire feeds the front , I am assuming he has power there , but has none on the red terminal of his ignition switch , all you need to do is follow that wire , and there has to be an inline blade fuse someplace , tige has them everywhere

Two red wires going into ignition. Which one?

[IDBoating]

I'm not assuming that. He should measure it with his meter. Then he (and we) will know for sure and debugging can proceed logically.

there has to be an inline blade fuse someplace , tige has them everywhere

Truer words were never spoken. I'm still not sure I know where every fuse is on my boat....

[IDBoating]

Just measure them both and let us know! The big question is whether you're getting power to the switch at all. No power on any wire means your problem isn't at this switch.

[dmbisbest]

No power to either red wire. Checked all fuses. They are good.

Starter does have power tho.

[dmbisbest]

And it is impossible to trace that wire through the side wall.

You should have power on the single red, If you don't that means you have. Blown fuse, the reason my picture doesn't show you the terminal with two wires is , I have e-button installed. Now trace that single red wire and find out where its connected , it has to have a fuse, the big red wire at the starter will have power because that comes directly from the battery terminal via the main disconnect at the back of the boat , also make sure as WA Said , that you also have power coming up to the front of the boat with a big gauge red wire to the common point between the blue viper box and black viper terminal wiring strip

Here is a little more info

Thanks. I checked all the fuses on top of the engine block. They are good.

On your second picture it mentions the 8 pin wire harness circuits with specific numbers. Where are those circuits?
