Car Forum / Driving, Maintenance, Tuning / RVs / November 2007Generator Problem
My Guardian RV 4700 generator, with only 7 hours running time and one year's age on it does not want to stay started. It worked just fine this past summer. Initially it would not achieve ignition, it just cranked. After screwing with it on a minor scale, it will now start, but it turns itself off after a couple of seconds. The length of time it is on, is very consistent. It goes off even if the start button is held down. I checked out the manual and know that it has oil in it. I am starting to suspect the control board. If it was a fuel problem like the filter, I would expect that the run time would not be as consistent as it is. Any help before I throw a couple few hundred at it? Check the fuel line on the suction side of the fuel pump. Possibel vacuum leak?

Lose mechanical fittings, especially in throttle or cut off area. Lose wires or faulty switch. Something may be stuck. Give it a good shake. Bad fuel, put in dry gas. Water in gas, put in dry gas. Check spark plug wire. Check fuel filter. Spark plug tightness. Carb mounted tight, same with manifold. Check to see what load it is driving into (electrical load) when starting. It may start under no load, then after a few seconds a load is switched in and it stalls. Things like to warm up. Try starting fluid and see if it runs longer. See if the spark dies before the engine stops turning. Check for lose grounding wire. Check air filter for clogs. Do all the basics first. 90% of time, it is the basics. >> My Guardian RV 4700 generator, with only 7 hours running time and one >> year's age on it does not want to stay started.

I suppose that I will have to jack it up and look at the fuel filter. When I stuck my finger into the carb, it smelled of stale gas. How would I go about flushing the gas out? >>> My Guardian RV 4700 generator, with only 7 hours running time and one >>> year's age on it does not want to stay started.

Try some fuel line/injector cleaner but just enough to clean things up. http://www.gumout.com/products.asp?products=1_1 Keep trying to get it started, using starter fluid sparingly. Once it gets running the gasoline (fresh) tends to clean things up along with the gumout. You can drain out the fuel tank and put in fresh gas which will speed things up. They key is to get the carb/injectors clean. Once it gets running it will be rough for a while but then it will straighten out, usually in less than 1/2 hour of running. All those solvents, especially starting fluid dissolve the oil on the cylinder walls. Get it into the cylinder in vapor form, use sparingly. I cringe everytime I use it, but sometimes the alternatives are very limited. Good luck there! It now runs as long as I want as long as I manually hold the choke open.

That's great Dan! Sometimes if you can get them to run a bit by whatever means, the problem just goes away. Check the automatic choke spring/mechanism if you have one. See if it works fine once it is warmed up. If you can, let it run for 1/2 - 1 hour and see if the problem is gone. >>>>> My Guardian RV 4700 generator, with only 7 hours running time and one >>>>> year's age on it does not want to stay started.

Take a look at: http://www.guardiangenerators.com/PublicPDFs/E1881.pdf Page 48 of the manual gives instructions on how to check the choke solenoid for your unit. I bet you can find the problem and fix it for the cost of parts. Look how far you have come already. Steve >> The choke mechanism appears to be electrical.

Look how far you have come already. Great link. When I start the engine, the solenoid moves the choke plate. It then closes it which shuts the engine down. If I manually hold it open, the engine will run. Whatever controls the solenoid, seems to be the problem. >>> The choke mechanism appears to be electrical.

Does the choke solenoid cycle open/closed every two seconds as described in the diagnostic manual? It should cycle only when the engine is cranking, but not when running. If so, my guess is that your choke may be closing too much. Is it set up according to the manual? Does it work as the manual describes? >>>> The choke mechanism appears to be electrical.

No, it only cycles once and then the engine dies. > If so, my guess is that your choke may be closing too much. Is it set up > according to the manual? > > Does it work as the manual describes? I think I have reached the point where I start to think that digging in more has unacceptable risk. I can easily do more damage than good at this point. Thanks for the help. I will be able to talk intelligently to the mechanic and not likely be taken too much. >>>>> The choke mechanism appears to be electrical.
