    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    My warning lights and scene lights are either Whelen LED, or Tecniq LED. Because my rig is used to support the USCG Auxiliary, I needed amber warning lights, but I wanted clear lenses. I was able to track down what I needed through my ambulance electrician friends, so the cost was a lot less...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    If you want lights, radios, and anything with a motor to operate correctly, it needs to have 12 volts AT THE ITEM. The factors affecting this are the amperage needed, the length of wire, and the size (gauge) of the wire. If my refrigerator was installed next to the fuse panel, I could probably...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    If anybody has halogen warning lights, and you convert to an LED bulb (Amazon, ebay), remenber to save your halogen bulbs. Why? These little bulbs sell for about $35 new, and used for $5-10 each. If you plan to convert down the road, your existing halogen fixtures aren't designed for an LED...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    Been chopping into some cabinets. I need to install my 12 volt marine refrigerator and a Broan electric heater. The Broan is rated at 1500 watts, but I'm only going to run it at 750 watts. That will give me about 2500 BTU, which will be plenty for my non-winter usage. The refrigerator's...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    It cost me some bucks, but I now have the complete build package of drawings for my ambulance -- framing, cabinets, compartments, electrical schematics and wire lists, and a full set of American LaFrance's wire color codes and numbering conventions. I started plowing through them tonight, and...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    Just when I'm convinced I'll never track down the official owner's manual for the truck---- I find that the gent who was the Medic Master Chief Engineer when the company closed down has all the build records. I believe he also has the capability to re-program the VMUX systems. I just ordered a...

    Converting Whelen 900s/Similar Scene lighting to LED?

    Very nice! Steel or aluminum? I had some Whelen light buckets that were about your depth, but a little shorter and longer. After I looked at making custom buckets, I lucked out and found 4 Whelen scene LED lights for the sides, and a pair of Tecniq K90 scene lights for the rear. I found Whelen...

    Buying & Building a Medium Ambulance into an RV – The FAM-BULANCE

    Springtime! That wonderful time of year when stuff that's been hiding in the garage all winter gets sorted (after I dust with an air hose...). I found 4"air vents that I'd thought were long gone -- I put them with the ones I bought when I couldn't find them. I now have 11... A pair of air...

    Ambulance Camper/ Expedition Rig Conversion FAQ

    It sounds like your battery disconnect relay may always be partly ON, possibly from a short that's feeding the relay control power line. The rear heat may be doing the same. Time to trace wiring with a volt meter or test light! Your ambulance wiring should be labeled regularly along each wire...

    Ambulance Camper/ Expedition Rig Conversion FAQ

    Probably all emergency vehicles have multiple parasitic power draws, ranging from radios to cell phone chargers to rechargable portable lights. As a result, vehicle batteries can go flat within 2-3 weeks. Even though a battery disconnect switch can avoid the problem, emergency vehicles are...

    Ambulance Camper/ Expedition Rig Conversion FAQ

    Pat and I emailed daily, with a few phone calls from time to time. He definitely was a positive influence on the building of expedition vehicles -- he was turning the module from a Wheeled Coach ambulance into a hurricane-escape trailer, complete with a custom made heavy duty trailer frame. "The...

    Ambulance Camper/ Expedition Rig Conversion FAQ

    Pat had medical issues that increasingly limited his mobility, but he still did what he could to help others. His experience as a fire chief for the DoD meant that the right way was the only way. He is missed by the many people he helped.

    M2 Freightliner Ambulance Conversion Project. 2007 Crew Cab

    Whatever it is beats me. I checked with my ambulance electrician friend, and he's at a blank as well -- he commented that he never had to do much with the VMUX equipment except sometimes replace modules. I'll keep on asking other friends.

    M2 Freightliner Ambulance Conversion Project. 2007 Crew Cab

    Considering their workmanship, shorter cables would probably mean wire nuts.... I checked with my friends, and the answer seems to be that that circuit is used to collapse the suspension so the loading height wouldcomply with KKK requirements. They used an odd way to say it, though.
