Finding a Generac generator repair guy/facility

Hi, IRV2 folks,

I've got a 2003 Scottsdale with a Generac generator on it. Was working fine, now won't start even though it tries. I can't find someone who will diagnose and repair this for me. Went through all the names on the Generac Authorized Service dealers list for my area, none of these folks wants to deal with an RV generator.

Any tips on who to look for / how to ask for generator repair? I suspect it's a simple part failure (fuel pump, spark plug, etc.) but need someone willing to look at it.

What is the fuel source?

Perhaps an outdoor power equipment shop could help?

I have found that some "small engine" repair places will work on them. Since it is the engine part that needs repaired, it shouldn't matter. See if you can find one in your area who is willing. I wouldn't limit my search to a Generac Authorized Service center.

Before you send your genset into the shop to be repaired you can go through the basics yourself.

Start with fuel, is there enough fuel in the tank, I don't know if you are dealing with a motor home or TT installation, but, in a motor home installation the pickup tube ends about a quarter of a tank from the bottom of the tank. In other words if you have less than half a tank of fuel, go put gas in and see if the genny will run. this is one of the most common "cranks but won't start" causes I have seen for generators in RVs. The second thing you want to check is your oil level in the genny, most of them have a low oil switch that will shutdown the genny or keep it from starting when it runs low on oil. In my experience all gennys burn a little oil, so if you use it a lot, you may be low on oil. Third, check the air filter. It is usually fairly simple to check, it could be clogged, especially if you run the genny in dusty conditions. Rodents are also fond of nesting in the air intake tract.

After checking all three of those it is time to get into basic mechanical diagnostics. I could walk you through all the basics later if you can't find a shop to diagnose it. Fuel pumps are one of the most common failures, along with worn out or fouled spark plugs.

When it comes to a shop, have you tried the RV dealers around you? They have to deal with genny issues all the time.

Good luck, Dave

Thanks for the details - I can try some more RV dealers, no luck so far but I WILL eventually find someone.

Given the age of this coach I'd like someone to do a complete service on it, so I won't hack around myself. I watched one mobile tech do that who was here for something else, I don't want to start messing with this, rather see what someone experienced has to say. I'm sure someone will help me - eventually! My offseason is coming up so I'll have all winter to resolve it.

Thanks for the tips - my money's on the fuel pump personally, given it does try to start but won't run -
