Can I bypass a starter capacitor to see if it is the problem why the motor is not working?

All the remotes click when activated but, the motor does not work. I checked to make sure all the door locks are unlocked and also checked for any resistance along the trolley assembly and pulled the trolley release and everything operates freely.

Sounds like more of a circuit/logic board problem than a motor..over the last 10+ years I've delt with a lot of openers that have had surge or lighting damage but never have had a motor go bad.

If it is the capacitor, the motor will just buzz for about 1 second. Dont bypass it. Capacitors are cheap. If the motor hums for several seconds, its a gear/sprocket issue. Also, make sure the traveller isnt all the way against the stop bolt.

Release the door from the trolly.. Pull the release lever. Then on the motor panel where the wires are connected you can jump 2 of the terminals to bypass all... Watch to see what happens. The starter capacitor gives the jolt extra electricity to start the motor so not smart to bypass the capacitor. Without the door attached the motor should run. If you are handy you can run a 110 volt wire directly to the motor then plug it in to see if the motor spins... REMEMBER 110 CAN KILL SO I WOULD RUN IT OUT OF A GFI FOR EXTRA SAFETY

Yes, you can temporarily bypass the capacitor to see if the motor will work. You should also verify voltage at the motor while another person operates the door to see if you get 110V.

It's the gear drive. There are kits online for about $40, if you're semi-handy you can replace it yourself. Search for liftmaster replacement parts.

SOURCE: Garage door opener motor doesn't work.

2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

SOURCE: Craftsman garage door opener 1/2 hp will not open door

It sounds like your chain is out of sync with the limit switches. Loosen the chain enough so that you can remove it from the sprocket on top of the motor unit. Now run the opener until the sprocket runs counterclockwise and stops. Now with everything attached and the door in the open position replace and tighten the chain. You are now in sync. You may need to tweak the up and down limit controls which are on the side of the motor unit.

This sounds like you will have to replace the logic board. Whether you repair or replace get a surge protector 900 joules or higher unless you want it to happen again. You can get replacement parts at Thanks BB

I have a 2004 sea doo with a starting problem. It will turn over 3 or 4 times and then just click. I have a new battery and have cleaned all terminals within reach.


I suggest you test the theory by bypassing the relay and/or energising the starter motor manually using a jumper lead, a suitable screwdriver or similar or a remote starter switch.

Can a starter drop dead with no previous indications of it going bad?

Hi Frank , what make vehicle ? Do you have any warning lights lit on the dash , SECURITY maybe ? Check engine light ? Did you check to see if there is battery voltage at the starter solenoid ? Did you check if there is A starter relay ?

Where are the black and red wires connected from the prestige aps787c remote car starter two wire yellow plug 2 pin transponder control output? i will also be using the dbal2 bypass module. thanks

The only 2 pin connector is for the transponder bypass module.
These wires are for the following outputs
2 Pin Transponder Output Harness #1123292
1) Red Battery (+) 100mA
2) Black (-) Output While Running 100mA

This connects your transponder key module to the starter, it activates the module when cranking to simulate a key.

a: When selected for while remote start on, the Black wire will be active at the same time ign. 3 becomes
active, and will remain active all the time the unit is operational under the control of the remote start.
b: When selected for output during the start sequence, the Black wire will be active at the same time Ign.
3 becomes active, and will remain active until the vehicle has started. This will be used for one time read
transponder circuits.
c: When the unit is selected for until ignition off, the Black wire will become active at the same time ign.
3 becomes active and will remain active even after the key take over and until the ignition in the vehicle is
turned off. This will allow the unit to be used for continuous read transponders circuits

Yikes! that sounds like the starter capacitor or starter relay.
Your meter must be able to show very low ohms to distinguish a short from a normal coil. Relay coils like that can be very low... like 10's of ohms.
If you bypassed the relay, then you are sending the compressor into over-current (because there is no starter capacitor) or the compressor is shorted.
There is somewhere a starter capacitor or "condenser" that basically gives the motor a boost to get it turning. These capacitors usually open up after a few years. You can get a new one at a refrigeration or AC parts store. It will be marked with a number like 22 uF. It is round or rounded and has a metal covering. Be sure to get the right kind because all this stuff you are working with is dangerous to make a mistake with.
When that capacitor is bad, you will hear the compressor hum loudly and then click. If you are just plain mean you will wait a few minutes and it will do it again... but what you are doing is going to ruin you compressor when there may still be lots of life in it.
On the other hand, if this has gone on too long, the compressor may be ruined anyway. But a new capacitor is much cheaper than a new compressor by a long shot!

We have a 100 ton press electric motor an a hydraulic pump.You have to hold in on the reset to make motor run.

The overload switch may have failed. Does the motor stop if you let go of the reset? If the motor (single phase) has a capacitor start, the capacitor may have failed partially which will cause overload because the motor just sits and hums without turning. If this is a three-phase motor, the overload button should shut off the motor starter which directly removes power to the motor. Don't jury-rig a switch to bypass the problem. Hope this helps!

Starter wont turn.

Hi and welcome to the site,

Initially, have the battery externally charged, checked and load tested.

Offhand, if the battery is fully charged/new and:
  • the electrical is completely dead, check the main fuse inside the starter relay;
  • if there is just a clicking sound, check, bypass (test), replace the starter relay;
  • if there is no clicking sound, check the start button switch, the engine ON/OFF switch, the sidestand and/or the clutch switch.
Of course if bypassing the starter relay and still the starter motor will not spin, then possibly a starter motor concern or more particularly the carbon brushes and/or the commutator segments.

Good luck and thank you for asking.

I am installing a bulldog rs 700 for my corolla 1998. I cannot start by the remote starter , and the bypass control module makes noise clicks constantly. So how will I do ? Please help me ! Thank a lots.

You do not require a bypass module, double check your wires to make sure they are going to the right ones, but again you do not require a bypass module for this car

2000 H.D. Sprotster; starter will not turn when you hit the start button, just get a clic. Battery is good and lights are on. Is this a starter problem or is there something else I should check.

Hi and welcome to FixYa,

Almost always, the click indicates that the starter relay is working or at least trying to.  Initial checks:
  • externally charge the battery and have it load tested (just to eliminate the remote possibility).  Necessary precaution if the bike is equipped with alarm/security devices;
  • bypass the starter relay by jumping the 2 big terminals on the nuts (not on the threaded portion);
  • expect a big spark;
  • the starter motor should spin;
  • if it does, then the starter relay contacts are pitted, burned or corroded and would require replacement;
  • if it will not, then a starter motor problem most likely the carbon brushes and/or commutator segments.
Postback results of tests.

Good luck and thank you for asking FixYa.
