Keeps cutting out when on tic over, some times when riding. Ken.

The Bunn Ultra-2 originally came with several circuit boards, including the main control board and a small memory board also known as the "TIC Clock". This little board, screwed in directly behind the main control board and has a small round metal circuit on it that looks like a watch battery, but it is not -- the metal "Can" contains the timing and memory functions for the main control board.
There is also a small battery inside the "can", which maintains the memory when power is removed from the machine. Over time, this battery will fail and you will see an error message on your LCD readout that says ":Bad TIC Clock". In the past you could just buy a new TIC Board from Bunn and install it and you'd be back on your way again. But, Bunn no longer sells the TIC Board and instead Bunn wants you to purchase a new Main Circuit Board that has the memory and timing functions built right on the new Main Board. The list price is over $200.
You can now purchase a TIC Board Rehabilitation kit from the Margarita Guys for under $50 which will replace the failed circuitry on the small TIC Board. Go to ebay and search "Bunn TIC Board" and you will see the kit available there. It includes all the necessary tools, 9 pages of detailed instructions and annotated photos, free Priority Shipping, and free phone access to their Bunn trained and certified Journeyman Technicians for any help you may need.
This should be the perfect answer to resolve your Bad TIC Clock message and the working errors that come with it.

Lamin, if your clutch sounds like an airplane, it's fully engaged, you need to replace it. If you already replaced it an you hear the common "tic tic tic", try replacing your fan clutch with a newer version OR have your software updated at the dealer, there is a TSB for it. Both problems are very very very common. While you're in there, replace your water pump. To make this job easy, cut a notch on the top of the shroud where the radiator inlet is.

It sounds like a shorted speaker or to many on one channel. It could also be a failed output device. I think the tic-tic is the overload safety cycling.

DORTHY DO YOU HAVE MANUEL? KEEP HITTING SET BUTTON UNTIL YOU GET TO ZONE?

It sounds like the spider gears inside transaxle is worn or broken causing noise and causing reverse not to work.

If the battery is old, it may no longer have the cranking amp it needs to turn the starter. If you have a multi-meter. Check the load on the battery when you get someone to start the engine, if the meter reads that it drops below 10.5 volts. You need a new battery, if the readings are good, then you'll need a new starter.

Good luck and keep us posted, a set of good jumper cables and another car may help get the engine started for now by boosting the battery.

Replace the tensioner pulley. If you take a look at it you will see a clean area towards the engine where the belt used to ride. The spring has become weak and it's leaning on a slight angle.
If I am correct, please look at the pulley, and come back and leave a testimonial and rate my assistance to help others that may experience a similar problem.

I HOPE THESE TIPS CAN HELP YOU MOSTLY WHEN A STARTER TICS IS A LOW BATERY VOLTAGE BUT IN SOME OTHER CASES IS THE STARTER THE STARTER CAN BE CHEKED REMOVE AN CAN BE SERVICED BY A GOOD MECHANIC BUT IF THE BATERY VOLTAGE IS OK AND THE STARTER IS IN GOOD CONDITION THE PROBLABLE CAUSE MAY BE THE START NEUTRAL SWICTH THAT IS LOCATED IN THE TRANMISIION LINK AND MAY BE THE CAUSE OF POOR TRAS PERFORMANCE TRY CHANGING OR CLEANING THE BATERY TERMINALS WHITH A LEMON AND SOME WATER

you need to bring all 3 blades to point at each other on the deck
do they all look the same?
aLL 3 should meet each other evenly with no more than 1/8th inch difference high or low point to point.
the stump strike could have bent the deck on that side
also be sure the fin side of the blades are pointing towards the deck when installed.
check that your deck is level on a level surface and the air pressure in all for tires are up to recommended pressure.
most of the time 14psi front and 10psi rear

Check for other problems. You might need to buy another FET as well. But this time don't put the FET back in until you make sure nothing can blow it.
