SOURCE: Low voltage

Most generators use a flyball type governor within the engine to control rpm; also there is a voltage regulator that tries to maintain voltage at about 115v. The voltage regulator varies the voltage to the armature increasing /adjusting magnetic force. Use a meter with htz or freq setting to adjust engine governor to 60 cycles. When the generator is producing 60 cycles, the engine should be turning 3600 rpm, max power range. At 3600 rpm the voltage should be 115 to 120 volts. Loading the generator will cause governor to try to maintain 3600 rpm. Check engine manual for proper adjustment of gonvernor and linkage. The governor mech should last the life of the engine, however governor system does wear out. Expensive repair. enjoy

SOURCE: Engine vibrates, shakes car at 1700 rpm, smooth at 2000 rpm

Something similar happened to my van, and it ended up being that I needed to replace a tie rod in one of my wheels. Hope this helps! I know this was posted awhile ago.

85 volts represents residual voltage. It is possible that your unit sat for an extended period and lost it's magnetism or the excitation system failed under load. check your manual for a procedure to "flash the field". If that is not successful, e-mail me and I'll tell you how to trouble shoot the failure.

Mig is not pulling enough amps. For example at 20V it is only pulling 85A.


With constant voltage, amps depends on wire speed. You would have to increase the wire speed (or larger wire) to increase amps. Also, any voltage loss between the machine and weld will reduce amps due to voltage drop.

Voltage drop. When in parked I rev up the engine, when it comes down, the voltage drops from 14 to 10, for about 5 secs. I think the truck will cut off but it immediately comes back up to 14.


If the alternator is weak, and you have accessories like the headlights or blower motor running, and the RPM drops below 600, the voltage could be below 12. It would depend on the load, RPM, and several other factors.

AC voltage is 275vac on the powermate generator model # PM069250......engine speed is 3750 rpm (max is 3600 rpm)......how do i lower the speed and the 275vac to a nominal 240vac output.There is no expert...


On the engines carb. is a governor rod should connect to the front case of the engine. This rod should have an adjustment to slow the engine speed. BUT,,, are you reading the generator unloaded or without any thing plunged into it? Once you have the generator loaded with a device, the voltage should drop to a constant 240vac. 150 rpms should not make that big a difference on the voltage output, and if running under load the RPM's should drop also..

Compressor drops to 80 lbs when sandblasting, should hold 110lbs.


The air pressure on your system is actually controlled by the orifice size at the tip. The tip wears very fast and the air pressure will drop accordingly. Install a new tip and retest pressure. The only way to increase pressure as the tip wears is to increase the rpm of the motor/engine. Also check for leaks in the system. If possible, start out with a smaller tip and lower engine rpm a bit then increase rpm as the tip wears. You can also play with the grit size as the tip wears. Slightly larger grit/sand will work better as the tip size increases and pressure drops. Good luck with you sandblasting project.

Engien revs and lights dim when i key up


You don't say how much power you  are running, but it must be quite a bit, or you have an amp you're not telling us about.  By keying up the radio, you're putting enough load on your electrical system to pull the voltage down which causes you lights to dim, rpms to drop, etc.  When you key off, everything goes back to "normal" which means no load so the engine will surge momentarily before it recovers.  Depending on how many watts you are running, you may also be affecting the alternator regulator.  Your alternator may also be a little weak.
