20 Most Recent 2001 Triumph Triumph Bonneville Questions & Answers


Hi, Markypup and the usual suspects are:
1. 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 preliminary 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.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. A failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen the gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from the intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

Hi, David before testing any electrical component in the Charging System 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 if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries.
1. 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.
2. To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
To do this with a meter: black lead to battery ground, red lead to each pin on the plug, start with the voltage scale higher than 12vdc and move voltage scale down in steps for each pin. Any voltage is a bad regulator.
3. On the other part of the disconnected regulator plug. Set the multimeter for Ohms x1 scale and measure for resistance across the pins of the stator. You should read something around 0.1 to 0.2 ohms for a 32 amp system.
4. Then check for continuity between each pin on the plug and frame/engine ground. The meter needle should not move (infinite resistance)(digitals will show infinite resistance) if the meter needle does move (indicating continuity)(digitals will show some resistance), recheck very carefully. If the meter still shows continuity to ground the stator is shorted (bad).
5. Set the meter to read A/C volts higher than 30 volts (the scale setting for voltage should always be higher than the highest voltage you expect or you may fry the meter). Start the bike, and measure from one pin to the other on the plug (DO NOT cross the multimeter probes! - touch them to each other). You should read roughly 16-20 vac per 1,000 rpm.
6. If the battery was good under load test, if the stator is NOT shorted to ground, and the stator is putting out A/C voltage, then the regulator is bad (most likely even if passed step 2)

Hi, Joehravitt46 to validate it is indeed a fuel issue spray starting fluid into the air cleaner then try starting if it fires up and runs for a few seconds then dies then you definitely have a fuel problem, you need to locate the fuel flow origin first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve not in the on or reserve position.
5. Vacuum line to fuel valve or VOS is cracked, broken, pinched, or missing.
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn.
7. Faulty fuel valve allowing fuel to enter the combustion chamber through the intake vacuum line
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working.
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.

It has been a while... but I believe there is a round access cover about 2" in diameter on the right hand side of the bike, forward part of the engine.

That corresponds with the end of the exhaust camshaft. 9_11_2014_6_00_28_pm.jpg
In this photo, it is chrome plated. They are held on by two philips head machine screws.

The points themselves are mounted on two plates. The first plate adjusts both sets of points, the second adjusts the difference in the two sparks.

That said, you might be on a wild goose chase. Most of the older T120s and T140s have already been converted to Boyer electronic ignition systems. MUCH more reliable, and much less maintenance. Smoother, and more precise as well.

Boyer conversion or not, the access plate in in the same place. It just might be a "pointless" ignition.

See these guys - they have very good telephone support - and will have Boyer kits in stock.

The points cover should be on the right hand side of the engine, at the end of the exhaust cam shaft.


point-location-xkwbzaj4qs1t5fjdyiiqbxtt-2-0.jpg
It is possible that the original plate was replaced by an aftermarket version with cooling fins. That doesn't do much, but it *looks* cooler to some eyes.

Most of these bikes have been refitted with Boyer ignition kits, so under the plate the points are no longer there. They are likely replaced with a sensor and magnetic sensor. That is a MUCH more reliable and maintenance free system.

If you do still have points, there will be two contact sets. The entire disk shaped plate will rotate to adjust timing and a smaller partial plate containing the second set of points can also be adjusted. That gives you control over timing, and difference between cylinders.

Really, I was a stickler for "original" on my bike, and I regret not changing to an electronic Boyer system as soon as they became available. Go for the upgrade. It's well worth it. A good shop can have it done in an afternoon, and you will never have to think twice about ignition or timing again.

Get a paperclip or a short piece of still wire. Put your fingers behind the side stand and trace to 2 wires from the switch. They will go to a little plug behind the side cover. Unplug the plug from the socket and 'jump' the plug with the wire. make sure you jump the right side, jump the side going into the harness, not the switch side. Don't leave it 'jumped' for ever. You might have a mishap if you ride off with the side stand down. This is more a temporary fix / bodge to get you home.
