Buzzing Ignition when key turned on, NO Start CT230?

[arnoldziffel]

I have a CT230. Used it a week ago. Everything fine.

Today, turned key to "glow plug" on position. Dash lights normal. When glow plug light went off, faint buzzing sound, NO Starter turn over.

With ignition switch OFF, if I turn on four way flashers, no lights BUT buzzing noise pulses at same pace as when flashers are working.

With ignition off, turn on headlight switch, NO lights, continuous buzzing until headlight switch is off.

Charging my portable battery pack to see if a "jump start" attempt makes things better.

Battery replaced 3 years ago.

Thanks for any and all suggestions.

Sounds like classic low battery voltage symptoms.

My bet is on poor grounding.
Check, not only, the neg terminal connction but the ground termal to the body of the tractor.
If you've attempted to start from a jump pack, your problem is still that there's not enough amperage to engage the starter bendix.
Given, of course, that your battery is still producing 12+v with 540cca's.
Dash and headlights are on different circuits.

Check your battery cables. The Bobcat ones are substandard.

When you check the cables actually pull and wiggle them. The split clamp on the terminals is known to corrode but still look attached.

Agree on this. Just replaced mine for 2nd time. Replaced battery too. Sprayed some anti-corrosion stuff on it this time. Smells a lot like spray paint..

I replaced mine like 5 years ago.....
James K0ua recommended using a paste ( I do not recall the name of it off hand right now) on the terminals.
Best stuff I have ever seen, no new corrosion and the positive cable still looks like the day I bought it from Bobcat

I have been telling people for many years to use No-Ox-Id, on battery terminals, But no one believes me. What do I know?. I only worked around and installed battery plants for many decades.. That all.. If you use No-Ox-Id, you will never replace a battery cable again. You will never have corrosion on cables. Using spray stuff and pretty little felt rings is about like pissing on them. Totally useless. But like I said, no one believe me, and you know what? ..........

Well, looks like one believed me I didn't lie did I ?

I believe you....

I bought it and its the best investment I have ever made

I do not make an electrical connection that sees any sort of environmental contaminant that I don't coat with it!
