Crown SC4510-50:
Shuts down completely using Forward/Reverse or any hydraulics

Event codes stored are 303, 111, 313 and is messaging low brake fluid which i need to look into also. The parking e-brake switch is loose and doesn't rock completely into engaging the brake when parking. Sometimes the truck will move after turning key on and off. Some times the hydraulics will work if you use them while traveling. 9/10 times truck will just power down completely trying to use and controls/throttle.

Alright !

Glad to hear the good news.

Crown BDI's can be notoriously inaccurate.

I tried my other crown's battery on it and it functioned correctly. Thank you very much for the help. I don't understand why the BDI on the display can be so high with that low of voltage. I'm charging up a spare for it right now.

SC 4500's don't use Brake Fluid.

The Return Spring for the Brake Pedal might be stuck due to rust.
You can lubricate it with chain lube.

Thanks for the reply

I dont know if they are simultaneous. I just scrolled through the events back to event 15 and those were the only 3 on the list. The BDI said 100% when i loaded for transport maybe dropping to 80% after getting back and driving it across the building and testing it out a bit. I'll check the water levels and voltage tomorrow and swap the battery out with known good one if I can.

Have you tested battery voltage ?

I'll bet the battery is drained, way below 20% State Of Charge.

That many error codes at one time usually means very low voltage.
