New starter, new battery, terminals all clean, battery tests 12.8 . Turns over slowly doesn't start any help?

Sounds like you have a weak battery, test the voltage. If battery is fine then your starter relay is the culprit. Clean all terminals in battery and relay, corrosion on the connectors will cause this too

1. Need a new battery
2. starter solenoid is defective
3. starter needs rebuilding...

Does Solenoid click when trying the electric starter? CAREFULLY jump the two terminals on the solenoid (SPARKS WILL FLY).. IF the engine turns over or starts, THE SOLENOID IS BAD. just replace it.
If it clicks when you are trying to start it electrically, use a multimeter (voltmeter) to see if you are getting 12v to the starter connection while you are trying to electrically start it. (+) lead on starter bolt and (-) to a motor mount bolt. If you get 12v+, starter needs rebuilding!

Hi Lee,

The starter requires substantially more current (amps) than the little wires and contacts that make up the start button and starter circuit. These small wires power a solenoid (an electro-magnetic switch) when the start button is pressed; which in turn closes a much larger contact that connects the larger battery wires to the starter motor.

You may have a blown fuse or fusible link, bad starter switch button, bad solenoid, broken wire(s) between the starter button and solenoid, poor connections at any of the terminals on these devices or a bad starter motor. Check the these circuits with a volt meter capable of testing 12 VDC or using a test lamp. Start with the one probe of the meter or lamp connected to a good ground or (-) post of the battery. The other probe should see 12 V (+) power on ONE of the starter button wires and on BOTH when the button is pressed. If not, work your way back to a bad connection or cut wire. Next, locate the solenoid. There should be two heavy cables and one or two smaller wires entering. The smaller wire is from the start button. Power 12V + should be on it when the button is pressed. If there are two smaller wires, one is probably ground or (-). If no power, check the wire for damage, etc. by following the wire back to the starter button. Once you have 12 V + starter circuit working into the solenoid, go to the next step.

Next, check the two heavy cables on the solenoid. One should have 12 V + power on it all the time and the other should have power only when the starter button is pressed. If you do not have power on one of the cables all the time, there is a bad connection,etc. between the solenoid and the + battery post. Check fuses, connections, etc. and make repairs. With power on one cable, press the start button A working 12 V starter circuit is required for this to work. If no power on the other heavy cable, the solenoid should probably be replaced. If you do have power out, it it still won't crank - check the cable between the starter and solenoid. Repair or replace as needed. If cable is good, the problem is likely to be the starter itself.

Good luck!

the solenoid for the ignition and starter has failed. Also remember the brake has to be applied to activate the starter system.

#! fully charged - good battery with CLEAN terminals and wire connectors. Starter is easy to rebuild.. If its not starting..try gently tapping starter with a dead blow hammer while holding the starter button down, if it turns over.. rebuild the starter...NOW. Make sue all connections are tight..

u must always hav 12.6 v for a coil ignition--u cud hav hurt the alternator - the relay is burnt too probly - the spark area and wiring seems to hav issues--get a clymer manual for detaild engine work--cdi is capacitor discharge ign

Hi. Depending on your skill level the starting point would be check "ALL" the fuses with a test light/multimeter. Next point would probably be check the starter itself, Again with a test light or multimeter you should have the main positive to the starter - make sure you have good battery voltage and check this whilst attempting to crank. Then the crank feed itself which is the small wire to the starter solenoid, Again check for good voltage whilst attempting to crank. If there is voltage on both then make sure the starter has a good earth by using the starter motor body as the earth whilst testing the main feed at the starter. If you have good main feed and crank the starter has failed. If not you need to post your test results for further help, Jon

The starter has to throw it's gear out using centrifugal force. The speed of the starter has to be enough to overcome the spring inside. It is either a little seized and needs to be rebuilt and greased up, or the battery isn't powered up enough to get the right speed to engage properly. In that case clean the battery posts and clamps well, then charge or replace the battery. To know if the battery is bad wait till it is charged... if it still doesn't engage try again with booster cables from your car etc. and see if it suddenly works fine.

Remove battery terminals and clean both posts and terminals
with sandpaper until you see shiny metal. The black coating is lead sulphate which has a high resistance to current flow both into and out of the battery. Charge the battery as not all batteries are charged sufficiently when new to do the job. Also not all new batteries are good batteries as they suffer manufacturing faults which allow them to discharge internally. some batteries are sold without the acid so check that is not the case.. Check all terminal connections including any earth wires.

Hey Josh,
Cleaning a carb is a little more that most people realize..it takes someone with knowledge and training to really do one right... take it to a professional..
