hdonlybob Posted May 26, 2015 Report Share Posted May 26, 2015 I also posted this in the General Information area, but thought the HDT crowd might understand it also... Still having trouble finding the problem with my Generator...Have tracked down most everything listed on the internet info....as in brushes, checked all volt specs in the wiring, etc., fuel, and so on.. Not giving up, but reason for post today is that apparently at some point this generator must have been added. Talk about a cobbled up frame to hold it...geesh...NO thought to getting the back cover off to see wiring and brushes....or removing it to work on.. What a mess.....this stuff really burns me up.... I have built a lot of stuff over the years, and never never would have done a stupid job like this.. We wound up cutting off a rear bracket and back plate to get to the area we needed... Then to top it all off, just after we started it began to sprinkle...then..yep you guessed it...all out rain.. My buddy stayed under the Motor Home and kept working while I put a large piece of hard plastic over my head and still got drenched... Look at the cobbled up framing on this job..

NeverEasy Posted May 26, 2015 Report Share Posted May 26, 2015 Bob, What is it doing/not doing? Maybe there is some assistance to be had. Make and model will help, too. I will look for info in the general area and see if it has any pertinent data. On edit: I looked at your other post and saw the same thing as above. Did you post the symptoms somewhere else?

hdonlybob Posted May 26, 2015 Author Report Share Posted May 26, 2015 Yes, I had a post for info some time ago.. We have videos and lots of information, just now really getting into it, as other place that looked at it gave up after basic checks... Original post is here: (it is a Honda EV6010) http://www.rvnetwork.com/index.php?showtopic=117605Cheers, Bob 1989 Safari Serengeti 34'Towing a 1952 M38A1 Military Willys Past HDT owner Link to comment Share on other sites More sharing options...
NeverEasy Posted May 27, 2015 Report Share Posted May 27, 2015 I am not a Honda generator expert. I owned an EV4010 in my old motorhome but it is gone. Forgive me if you know this stuff and I am preaching to the choir but for what it is worth, here it is. Symptom: Engine starts, red light does not go out, engine dies as soon as the start switch is released. If you have not yet replaced the brushes you might want to start with oil pressure and field current. The startup sequence goes like this: 1. Press and hold start switch 2. The control board sends 12 volts from the battery to ignition, fuel pump, choke heater (if equipped), start solenoid, and field flash. 3. Engine turns over and starts. 4. Oil pressure comes up and removes ground going to the control board. 5. Generator voltage comes up, creating a generated field current, and tells the control board to keep the engine running if oil pressure is good. Run light comes on. 6. Control voltage to the control board (4 & 5 above) cuts off 12 v battery to the starter solenoid AND field flash from the battery. 7. Release the start switch and the generator should still run. There are two types of these generators: Bridge rectifier type: Field current is created by a bridge rectifier that took the AC voltage from the generator (after the battery excited the rotor when holding the switch in), rectified it into DC and sent it to the rotor via the brushes to create self-generated voltage when the switch is released. Automatic Voltage Regulator (AVR) type generators (pretty sure the EV6010 would be this type) use the AVR to create the field current and regulate the output through a combined effort of field strength and engine governed rpm. This is what I would do: Check the resistance at the oil pressure switch to chassis ground with the wire to the control board removed. It is usually at ground level. Mash the start button and insure the ground goes away. Replace the wire. Next, if the oil pressure opens the switch, the next thing to look at is alternator output with the start switch mashed. Put an AC voltmeter on the output and mash the start switch. The battery will flash the field and create a nominal 80-120 volts out. If there is an output, the brushes, rotor, and stator are good. If the AC voltage goes away when you release the start switch then the problem is very likely the AVR (probably located in a control board of some sort).

Deezl Smoke Posted May 27, 2015 Report Share Posted May 27, 2015 Good grief!!! What happened in that bottom photo?............................ After being under my bosses dad's southwind, I'm not so sure that that is a afterthought instal. ? His southwind was on a john deere chassis. The fab work on many of the items underneath was appalling. Not much different than what you are seeing with your generator. I'm a work'n on it.

Thanks for the info.. my friend is the guru guy and has been checking all the voltages, etc..... I will give him this info to check out also...

Deezl...yep good picture of Ol' Bob trying to keep dry.....that piece of heavy plastic actually had about a 4" drilled hole in it pretty close to the center, so it balanced on my head pretty good...as long as the wind didn't get too strong... I was sitting on my handicap scooter, scurrying back and forth from my garage getting different wrenches and stuff for him...new use for the scooter that really helped a lot. Saved a lot of pain on my legs and back today.... !!

Jaydrvr Posted May 27, 2015 Report Share Posted May 27, 2015 http://www.pinellaspowerproducts.com Call this guy. He helps keep my Honda running, and is the national expert on Hondas. He also has repair info on his website. The symptoms sound familiar, just can't put my finger on it at the time. Do you have the factory repair manual? That might help.

Wrknrvr Posted May 27, 2015 Report Share Posted May 27, 2015 Check out pinnelas power you tube video's as that will help understand this unit and its operation. then call pinnelas Power once you have followed his diagnostics. Also that frame looks like it is the same as the generator that I worked on. safe Travels, Vern Link to comment Share on other sites More sharing options...

NeverEasy Posted May 31, 2015 Report Share Posted May 31, 2015 Bob, How is the generator repair coming? The Pinellas Power videos were superb. They should be watched starting with "Honda EV6010 no start 1.mpg". The video is very informative. They were lengthy but it took that much time to take us through all the possibilities even though the open wires and the number of them in one case is not likely. After watching, I put together a document (giving credit to Pinellas) that can be carried to the generator. This document ties the reading and test points to the wiring diagram in the owner's manual. If anyone is interested in the Word document, send me a PM.

hdonlybob Posted May 31, 2015 Author Report Share Posted May 31, 2015 My friend who is working on the Generator will be here again this next week, and he understands as well as has the tools to follow up on your comments. I have forwarded to him all the comments and advise here, much of which he has already checked out. I really appreciate all the comments and help...this is a really great forum.
