Question about 1996 Honda CBR 600 F(3)T
The voltage regulator is getting too hot @
Posted by Anonymous on
Hi, Anonymous 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)

SOURCE: change headlight
Doing a search I saw your question come up, hopefully this is not an old question. ANyways, under the front edge of your fairing there is a small black rectangular plastic piece held on with 2 screws and two clips. Remove the clips by pulling on the centers, they should come right out, this will give you access to the back of the headlight. There you will need to unplug the headlight and the give the light a turn and it should come out of there. Make sure not to touch the new bulb with your bare fingures as this will shorten the life of the bulb, clean with alcohol if you do, hope this helped.

SOURCE: starting problems
Check the compression. If it has low compression it will always be difficult to start. I have the same bike. It is a really good starter, comparatively to other older 'cycles I own. 1) Check the fuel level in the tank, and be sure to turn the fuel switch (left side of bike below tank and seat) to On, or even Reserve 2) In stock tuning, my bike likes full choke for cold start, in any ambient temperature, it likes to warm up with the choke on, until it starts to sputter from the rich mixture. 3) I believe this bike has vacuume tube that goes to the fuel petcock, this shuts off fuel to carbs when bike is not running. Thus if the bike has not run in a while, or the carbs drained, it will take several start attempts to get the carb float bowls filled. 4) This bike is hard to start if the battery is old or marginally charged. 5) Also pull the spark plugs, if they are brown, or black, change them. 6) check the air cleaner, if it is too dirty it will essentially act like a choke

SOURCE: battery problems
After you start the bike put the headlight on high beam. Rev the engine and the light should get a bit brighter. If it stays the same or dims the battery is discharging.
If you have a meter, take off the seat and start the bike. Place the meter in DC Voltage mode and place the red probe on the + side of the battery and the - probe on the negative side. It should read 12v to 14v. Start the bike. The voltage should rise to over 13V or at least higher than it read when the bike is not running. If you rev the engine the voltage should also rise a 1/2 volt or so.
If the voltage remains the same or decreases you have a charging problem. Here are the two most likely fixes.
Tighten the battery connections.
The rectifier is not working. It is located on the right rear of the bike under the seat fairing.The rectifier converts the AC voltage coming out of the alternator to DC voltage which is what the battery needs to stay charged.

Two things can be happening, either your charging system isnt doin the job, or you have a short thats draining yer system... so
to answer your question... start by fully charging your battery, then put a volt meter on it and turn your bike on.... the volt reading should increase.... if it doesnt - you got a stator or regulator problem - if it does..... you need to trace your wires for a possible ground to yer frame

SOURCE: cbr 600 f3 will not start
wow, 7 years without use! try to check if the fuel pump motor is still working... also check the fuel lines if its clogged.. I hope you get your bike up and running again... feel that adrenaline rush when going 100+mph.. hehehe.. have a good one bro...
