What is the the volts fore the came sensor


The cam sensor outputs voltage pulses when the engine is running. The sensor is powered by the engine's computer, which typically provides 5VDC to power the sensor. With the engine not running, turn on the ignition switch. A cam sensor has three connections: Power (5VDC), signal output (% or 0 VDC varies with cam position), and ground return. Measure the signal voltage from the cam sensor wiuth repsect to ground. If it is 5V, slightly turn the engine's crank with a wrench until the cam sensor signal drops to zero volts. You should be able to see the signal voiltage switch between 5V and 0V while turning the crank slowly. If so, the sensor is working properly. If the signal doesn't change, the sensor is likely defective and should be replaced. They do fail.

Engine speeddoes not raise when put under load but produces power


First verify that the breaker for the outlets is not tripped and make sure that the generator is running at full operating speed. let it run for 5-10 minutes and check for output power. If there is nothing, there are two possible problems. One could be that the automatic voltage regulator is bad. The other is that the field needs to be flashed - a high possibility if the generator has not been run in a long time. There are many videos on the internet that show you how to solve both of these problems. Just do a search for No output from a portable power generator.

I have a troybilt 7000 gas generator that trips the main output breaker when under a load after 5 minutes


1. Make sure that the generator limit is not being exceeded.
2. Try checking and raising the rpm. If the engine can not sustain the load from the generator, it can/will trip the breaker.
3. If the carb is dirty or the engine runs poorly it can trip the breaker. Tune up the engine, clean the carb, make carb adjustments to correct substandard running conditions.

My 1990 Honda Civic battery keeps draining the alternator is running well between 13 and 14 when the battery got low it started to lose power while I was driving I replace battery in it was already down to...


Not sure I follow your story.
Have you checked the output of the alternator while it is on the engine, and is it between 13 and 14 volts ? Does the battery lose power while the engine is running or after you turn the engine off ?
Is the alternator output normal but not reaching the battery ?

Generac 5250 with a 8 hp Honda engine. Runs fine, no output


Take a resistance reading across the brushes with and Ohm meter. (not running) You should read a low resistance. If you have no resistance across the brushes then then either the brushes are not mating with the armature or the the armature is open.
IF you have resistance then the AVR (Automatic Voltage Regulator) in the endcap has failed. With the engine running and the Brush block disconnected you should have 4 - 12 VDC on the two wires going to the brush block. No voltage = bad AVR.

Thanks for choosing FixYa.

No power output from Briggs & Stratton ProMax 7500E generator


You may have exciting field broken. Look for a fuse or wire break.

No Power Output


Okay, this is going to sound kind of hard but you can do it...you need to flash the field and try to get some 'excitation' back to the windings. It's a bit of a deal but here's how:

With gen not running, plug the battery charge plug in to the charger output and you need to reverse the leads at the battery. Hook the BLACK to the positive post. Then, just touch the red to the negative terminal for a second or two. That's it!
Then...start gen and check output. If it just needed a flash, that will do it, I'm serious!

There is absolutely no voltage output. What


My generator has a switch to turn on the output, you must turn it "ON" to get power.
