Any generator experts out there?
Greetings,
I have a Westerbeke 4.0KW gas genny in my boat, and I'm experiencing the following: The genny runs like a sewing machine, and when first started, the voltage settles right at 115. When a load is presented (A/C for example), I'll get the typical drop from the load while the genny adjusts, and then the genny will settle back to around 115. All is well at this point. The problem is, when the load is removed (when the A/C cycles), the voltage rises to 150 and stays there. I notice an increase in engine speed as well. My initial thought is that the voltage regulator might have gone south, but I don't know if this would explain the rise in engine speed. I guess if the regulator doesn't control the voltage, the engine speed will rise accordingly to satisfy the higher voltage, but I'm no electrical engineer, so it's just a guess. Any input would be greatly appreciated! I'm planning an anchor-out this weekend, and with the rains and heat/humidity in FL, I can't be without A/C!!! |

Many thanks for everyone's input! I spend a couple of hours troubleshooting the genny on Saturday morning, and found the culprit. The governor was working properly, but wasn't returning the throttle to the idle position after the load was removed. Adjusted the linkage from the governor to the throttle body did the trick, in association with adjusting the governor to attain the proper voltage. I now need to throw a hertz meter on it to finalize the adjustement, but it now purrs at 120V, settles in at 120V under load, and returns to 120V when the load is removed. Now if I can figure out how to keep my A/C from cycling so much, I'll be in good shape!! |
