Triumph... | Answered on Nov 06, 2019


Hi, Whatsupkimis the best way to charge a battery is slowly. I like to use this analogy, would you rather be awakened from a deep sleep with gentle nudging or a violent kick in the rear.
1. Remove the battery and check for corroded or damaged terminals clean any dirt, corrosion or electrolyte that is on top of the battery as this will cause premature battery drain, inspect for cracks and swollen/expanded sides which are a sign of overheating and replacement should be seriously considered.
2. Acid plate type batteries should be checked with a hydrometer with recorded readings for each cell to be compared with after charging readings and for sulfation, the cell will appear milky, and incorrect acid level. Fill low levels with distilled water to the upper level and remove acid from overfilled cells with hydrometer until the level is at the upper mark and dispose of acid in the sink mixed with a quart/litre of water.
3. Connect a voltmeter set on the DC scale to the battery and record the reading for comparison after charging.
4. Attach a drain hose that is not pinched, kinked, or plugged to the nipple on acid plate type batteries and let the other end hang into a plastic or styrofoam cup.
5. Connect a 1-2 amp trickle charger that has an automatic charge rate reduction if possible and let charge for 24 hours.
6. After charging recheck each cell with a hydrometer a 100% fully charged cell will have a specific gravity reading of 1.270-1.280 and 1.180-1.190 has only a 25% charge battery should be load tested and considered for replacement if necessary. Reconnect your voltmeter and
any readings in the 10-volt range means you have a dead cell and the battery needs to be replaced. Readings between any 2 cells of 50 points or more indicate the battery has failed and needs to be replaced.
7. No maintenance AGM or GEL batteries need to have a voltmeter reading of 12.8-13 volts for a full 100% charge and 12.2 volts is only a 25% charge and should be load tested and replaced if necessary.

4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.

Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
18. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
19. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
20. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.

2005 Triumph... | Answered on Nov 05, 2019


Hi, Holden1112 before testing any electrical component in the Turn Signal Light Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, "AGM" batteries fall into this category more so than lead-acid types, also before diagnosing any turn signal/running light/parking light issue make sure the bulb is good and the light fuse has continuity with a test light. If you have replaced your OEM lights with one or all LED lights you are going to need a load equalizer.
If no turn signals are working the cause could be a faulty turn signal module/flasher or the connector going to it, look for corroded, loose, or broken pins/sockets. Contact spray cleaner is great for removing corrosion.
If your turn signal comes on but takes several seconds before it starts flashing you may have dirty contacts in the turn signal switch/button, the switch needs to be opened up and cleaned also the flasher may be starting to fail. It should be noted that cold weather will only exacerbate the situation especially when temperatures drop down below freezing and the location of the component, turn signal switches on the handlebar are at the mercy of the oncoming freezing 70 mph wind and makes it hard for the contacts to do their job covered in frozen grease/grime
If all four turn signals flash at the same time like hazard lights even though you only pressed one turn signal button then you have a LED light in the circuit and need a load equalizer that can be purchased from any motorcycle parts supplier.
If your speedometer does not function properly it will have to be fixed first because your turn signal module gets the data from the speedometer for normal turn signal function.
If your front turn signals don't work use a test light to check for power and ground at the bulb socket, then start backtracking the wiring through every wire connector to the turn signal switch/button and check for continuity, go all the way back to the fuse if necessary to find the cause of the malfunction.
If your rear turn signals don't work check your rear fender wiring harness connector first, look for, corroded, broken, loose pins/sockets, power, and a good ground, the harness connector is usually located under the seat on the front of the rear fender then keep tracing the wiring look for obvious harness damage caused by the rear tire.
If you still can't find the malfunction backtrack from the rear fender wiring harness connector.
If one side does not work you could have a faulty turn signal switch or module check for continuity.
