TORO ex wires to the back up battery are burnt

Hi, an older user here but more a follower but I do have a question that someone might have the answer.
I have a TORO ex sprinkler controller, the owner before me apparently put the switch on the charge option

and put in a regular 9 volt alkaline battery, the leads look burnt and broke off.

Is this unit serviceable in that I might take it apart and re-solder new leads to the main board.

If I can it certainly would be easier than replacing it as otherwise it works great, only thing is in a power outage I lose my program.
Would be a help if someone has done this before, thanks....Ernie

Here is what the unit looks like, you might have to copy & paste the link:

You maybe get to be the first. Take lots of photos, and give it a shot.

I must be slow, how do you put pictures on here?

Rainbird Model # SST-400in, Simple Set Timer Indoor 4 Zone

Just put this in replacing my older TORO ECx, easy set up (don't like the wire connections but I guess they are OK) my question is the clocking mechanism, the clock loses 7 to 8 seconds a day, I know that might seem trivial but that's 46 minutes a year....I find that way too much slack in the clock. I don't see any way of making adjustments either.

Just wondering if anyone else has had that problem with these units, if so there will be no need for me to return if they all have a poor clocking system. My old TORO ECx never lost a second, was more accurate than my watch.

Any experience is greatly appreciated and might save me from returning this one and replacing it with another Rain Bird.
Thanks a lot!.....Ernie[/IMG]

Let the controller run awhile. It might have some self-correcting ability for the time of day. I personally never worried about the precise time the controller displayed, since the lawn didn't benefit by accurate-to-the-second controllers. Lawns did just fine with motorized controllers you couldn't set to exact minutes, let alone seconds.

Rainbird Model # SST-400in, Simple Set Timer Indoor 4 Zone

Thanks, I will try that, I guess my concern is we live here in Florida for about five months and gone 7 months so that means a loss of a half hour or more in our absence, not earth shattering but I have never had a clock, watch or any clocking mechanism that badly out of time, the timing is simply a chip on a board and is usually extremely accurate like my old Toro it was more accurate than any watch I ever had.

I see a 1-800 number for Rainbird, I think I will try them tomorrow as I have had this working for several days and it is 7 to 8 seconds loss in 24 hours.

Will post the results.

As I mentioned in the previous message my Rainbird was losing 7 to 8 seconds per day which might seem paltry in the great scheme of things but that's almost an hour a year.

So I went to Home Depot and bought another Rainbird but instead of the 4 valve I bought the 6 valve unit and just plugged it in, set the clock and timed it and as suspected this unit lost the same amount of time right to the second.
So the problem is I would guess is the clocking chip that must all have this fault built into them.
An hour a year loss in any clocking mechanism is way out of bounds.
I will keep the unit (returned the 6 valve one to HD) and put up with its inherent clocking fault.

The other issue is the method of connecting up the wire leads where you have to get a screwdriver, push in the plastic clips and shove the wires into a slot, if these are braided wires...good luck, I had to put solder on them so as to make them rigid enough to accept the wires. On the plus side the unit is as they say "Simple Set Timer" easy to set but a few faults but also a great buy at $50 US plus taxes.
Thought others might like to know how my Rainbird turned out.

Would I buy again....maybe but I would check out others first as my former TORO had an excellent clocking system.
