Did I Just Fry My RV's Power Converter?
I was plugging in my 1986 Prowler (26") and heard a snap. When I went inside I smelled an electronic burn, nothing was on fire but the following day I noticed the coach batterys where not charging. Fuses are all OK and the batteries come up when plugged into the truck. Is this a small of large problem/fix

Let's see if I can help you determine if this is a small problem or a large problem. The fact that you smelled an electric burning smell may indeed confirm that you have damaged your RV's Power Converter.
You mentioned that you had checked all of the fuses in your travel trailer; the fact that you heard a snapping sound when this happened may indicate that you actually popped the circuit breaker for the 110 volt circuit that your Power Converter is plugged into. You need to look for the electrical compartment for your trailer and check for a tripped circuit breaker. Unfortunately I cannot tell you the exact location of your year and model trailer's electrical compartment. It could be in an inside cabinet of the trailer or in an outside storage compartment.
Once you find the circuit breakers check to see if one of them are tripped. If you find one tripped reset it and plug your RV back into electric again and check to see if your house batteries are being charged by the Converter. If they are not charging than it is a pretty good indication that you may have indeed fried your RV's Power Converter and possibly other parts of your RV's electrical system.
There are no user repairable parts on an RV's Power Converter so do not attempt to open it up and see
if you can fix it. Your best bet is to have a Certified RV Technician check out your electrical system and replace your Power Converter if needed.Preventing This From Happening In The Future
There is a pretty good chance that the problem that you are experiencing was caused by the 110 volt power source that you were plugging your Travel Trailer into. It could have been caused by voltage being too high, too low, damaged wiring, etc. Listed below are a couple of steps you can take in the future to prevent this from happening again.
1. Make sure that the circuit breakers on the power source that you are plugging your RV into are off before you actually plug in. Once your travel trailer is plugged in you can turn the circuit breakers back on.
2. You should also purchase a Surge Protector
for your Travel Trailer. You simply plug your RV's power cord into the Surge Protector
and then the surge protectors plug gets plugged into the power source. The Surge Protector will help prevent electrical problems with electrical systems you are plugging into from damaging the electrical system on your RV. These surge protectors are available for both 30 and 50 Amp electrical systems. For more information on Surge Protectors read the answer I gave to: Are RV Surge Protectors Safe?Over 1,500,000 successful roadside rescues—Good Sam RV Emergency Road Service
Following the steps listed above will greatly reduce the chances of your RV's electrical system from being damaged again.
I hope that this information has been helpful to you.
