120 x 80 % = 96 volts / so your voltage meets minimum requirement.
Maybe the clock motor is bad
Replace PB module

SOURCE: Wiring of Intermatic T8845pv

I believe the number you gave is fir the 14 day timer. Here is a link to the manual for it. Notice the not to use only one silver pin.

SOURCE: I just bought an older

I think you have the ET70215C SPDT
If this is not your timer, then add a comment.

Manual for ET70215C (same manual is for other models too)

Just as you figured, timer has selectable voltage.
Page 28 shows wiring diagrams and jumper settings:
Timer comes with a jumper, and then you select with voltage by installing jumper

Sample wiring diagram below shows 120Volts:
ET70125 appears to have 8 terminals.
Some models have 5 terminals.
There are many ways to wire this timer. Off hand I can think of 10 different ways.
Add a comment if you need help with a specific project.
In any case, the clock terminals are 1 and 2.
To put voltage to the timer switches in the simplest wiring options, is to put a jumper wire from terminal 2 to 3
If you are using 240-277 voltage with two hot wires, you still need to jumper from clock terminals to switch terminals. For example one jumper wire from terminal 2 to terminal 3 & then second jumper wire from terminal 1 to terminal 6

Sounds like the OFF tripper is worn down.
Timer needs to be replaced unless you have Intermatic-brand timer.

Intermatic is only company that sells plastic replacement trippers for their timers.
Except Intermatic on-off trippers are typically red-green.

I installed a new Intermatic timer, model # T8805P101C, it works manually but the wheel doesn't turn to automatic set timings

If the dial does not rotate but manual override works, then the timer is wired incorrectly or polarity of line is reversed or you are connecting to 240Volt line instead of 120V.
1) You have wires from breaker box reversed with wires that goes to sprinkler solenoid. Switch black wires and see if that corrects problem.
2) Check that breaker supplying voltage is 120Volt.
3) Test if black wire from breaker tests 120V to ground wire, and test that white wire from breaker tests 0 volts to ground.

There is a silver pin that fits into the periphery of the timer. I think this trips the smaller dial to rotate. If the sprinkler is set to go off at 4am, where should I place this silver pin for it to...

You have Intermatic sprinkler timer.
The silver pin inserts into the yellow dial at 12:00 midnight, and it rotates the skipper wheel.
Skipper wheel is necessary only if you want to skip certain days of the week, otherwise the timer cycle repeats each 24-hour period.
To skip a day, the skipper pin is pushed down for that day. Leave skipper pin up for days you want to water.

One of the two timers is not rotating

If timer dial is not rotating, then clock motor is bad or timer is not getting 240Volts.
You posted under T104 which is 240Volt timer and uses WG1573 clock motor.

To test voltage, test across terminals 1 and 3 for 240Volts.
Also click override lever to see if Load turns ON. If Load turns ON with override, then timer is getting correct voltage.

I have a GM 40 Series Multi Voltage Commercial DPDT time switch .Voltage reading across L1 L2 is 240. Orange and green light are both energized wired NO COM water heater not turn on.

Online manual for GM40:

You own a high-quality time piece.
I have defrost versions of same timer and have tested aspects of the timer, and own few FM1 series clock mechanisms for various projects.

Complete run down for setting GM40:
1) For 240Volt the dip switches are set: Please set dip switches before applying power to timer.

2) Line wires are the Hot wires from breaker box.
Line wires connect to terminals L1 and L2N

3) Load wire are wires that go from the timer to water heater.

4) Jumper wires are short lengths of same gauge wire.

5) There are many ways to wire GM40 timer
Open manual and look at wiring diagram titled: Controlling one 240VAC (Dual Phase) Load

6) A jumper wire is added from terminal L1 to COM
Another jumper wire is added from terminal L2N to COM2

7) Load wires going to water heater are connected to NO and NO2

8) Following image shows typical FM1 timer dial:
As timer dial rotates the pins move small red switch that turns Load on-off.
Move pins in-or-out to control Load.

9) If you are uncertain about your pins, then set 20 consecutive pins one direction and then manually rotate dial and watch green indicator light turn on-off.
Put tester across NO and NO2 terminals and check when 240V turns on.

10) If you have defective timer, contact Intermatic:

How do I install a T8845pv sprinkler timer. What do I attach to the two yellow wires

The timer is used to power a low-voltage sprinkler solenoid valve.
A solenoid is an electrical switch that opens and closes a gas line or water line.

The yellow wires go to your sprinkler system solenoid valve.
The solenoid is the valve that turns water on-and-off.

The 120Volt electric cable that runs the timer connects to the Line and Neutral terminals.
Black to Line terminal, white to neutral terminal

The clock repeats each 24 hours.
Lift and rotate dial until current time lines up with silver pointer

The skipper wheel has pins >> press pin down for each day you do not want watering
Rotate skipper wheel counterclockwise until current day lines up with 14 arrow

Put tripper pins on yellow dial
Each pin represents 12 minutes of watering
To water for 48 minutes, put in 4 consecutive pins
Put pins on wheel at the time you want watering to take place.
To water twice a day, put pins at two different times, and do not put any pins between those times.

Sounds like you need new ON pin


The ON-OFF pins rotate around until they come in contact with a lever. The clock motor pushes the pin forward until it clicks the on-off lever. The pins are softer metal than the lever, so the pins wear out.

If you need a new T-103 timer some day > the new timer mechanism can snap right into the old box without changing boxes.

If the dial is not rotating, then you can replace the T100 series 125 Volt clock motor (the T103 clock motor is 125V)

The clock has stopped. I have to turn it manually. Its an outdoor timer with a cover.

If the clock dial does not rotate >> and the manual override works >> the the clock motor is bad.

The clock motor is replaceable. Snap out the insides, and the clock is attached with 2 small screws >>> sometimes these take a start screwdriver from the auto parts store.

On the inside cover of your timer is a sheet showing the clock voltage. Some clocks are 240 Volts, some are 120 Volts.

The back of the clock also has identifying numbers.

You say the timer is outdoor. A pool timer is probably 240Volt timer, with a 240Volt clock.
If the timer controls the sprinkler or lights, then the clock motor is probably 120V, with 120V clock motor

Grainger sells 120 and 240 clocks for the T100 series timer

A+ sells a long list of Intermatic clock motors

If your timer is an Intermatic, you can also buy the whole timer, and then swap the insides without changing the box.

How to wire a PB913N timer

The timer has 4 terminals the 2 under the clock portion of the timer are for 120 VAC power to run the timer . the upper 2 terminals are the contact switch terminals which are opened and closed by the setting tabs of the timer to turn the item you wish to control on and off.
