Here's another one for your notebook - Freightliners have a battery disconnect switch on the floor to the left of the driver's seat (just in from the door). The truck's wiring is usually set up so if the switch is on, the truck marker light over the cab will always be on. Turn the switch off...

By the way - on a Medic Master, the AC really does better if the front panel HEAT/AC switch is turned on. The module is in charge of heating & cooling, so set the module's temperature for a littrr cooler than you want the AC to run at

Welcome to the club! Try to get the Medic Master manual that came with it if you can - it helps. Otherwise, if you buy one with the VMUX digital panel (touch screen), I have a manual for a Medic Master with digital controls. It won't be perfect, but the same electricians wired all of the Medic...

Thanks for the info! I found out that Milhoff Machine also makes a portable vise. Milhoff is 15 miles away from me.

Nice vise! My garage vise is a 50 year old Wilton "bullet" vise that I got for zip because they couldn't find new jaws for it -- I remachined the vise to match the new style jaws instead. Unfortunately, it's not portable unless I hoist the bench into the ambu-buggy. If it ever dies, I'll look...

Good info - thanks. I have the 24 valve 5.9 on mine - it's a 1999 Freightliner / Medic Master. Do the plug in diagnostic tools run into a lot of bucks, or are they just a computer program with some cables?

Amazing what a computerized engine can tell someone - back in "the old days" (my days), it was all purely mechanical measurements, and an engine that "might" have something electrical on it. My old D-8 pussycat had the 13000 engine, and the gasoline pony engine had an electric starter, along...

Today, I FINALLY got the Alcoa aluminum wheels switched for the steel wheels that she came with. MNtal traded me the Alcoa wheels after he went to larger wheels and tires on his ambulance, and they've been sitting waiting for the right opportunity. I had new wheel studs installed a few weeks...

If anyone is looking for amber lenses for Whelen 97 fixtures, they normally cost about $40 - but there's a guy on EBAY selling used amber lenses for $15 plus about $5 for shipping: http://www.ebay.com/itm/WHELEN-97-SERIES-AMBER-LENS-USED-/112495859711?hash=item1a314697ff:g:Q1QAAOSwFFZZd91a

If anyone out there is looking for amber lenses for a Whelen 97 fixture, check out this EBAY listing -- $15/each: http://www.ebay.com/itm/WHELEN-97-SERIES-AMBER-LENS-USED-/112495859711?hash=item1a314697ff:g:Q1QAAOSwFFZZd91a

It sounds like the easiest short-term solution is to paint your existing lenses to match the body - then the insurance company and the PD are both happy.

A quick Google search came up with Abbey Color. They make solvent based plastic dye.

Another thought might be to leave the light's bulb as-is and to look for a dye that you can use on the inside of a clear lens. Plastic dye is more available than bulb dye, and you may be able to even use something like a light coat of a green auto paint.

Green lights will be a challenge. Green is not used for a warning light, other than rarely in a lightbar. The only colors I have seen for a body-mounted warning light are red, blue, amber, and white. Generally, these colors are achieved through colored plastic lenses. Unfortunately, the lenses...

Since these warning lights showed up on all kinds of vehicles, lenses are available from many suppliers other than Whelen. I periodically do a google search on the Whelen part number, and I've found complete fixtures for as little as $10 plus shipping. Normally, the lens sells for about $40...

Soak things in mineral spirits for a day or so. Spirits should be mild enough to soften the adhesive without crazing the plastic. I had to super-glue a few of mine when the screws pulled the lens mounting boss loose, but the super-glue worked fine

The insurance company is probably unhappy with red or blue lights. When I bought my ambulance, the dealer (PA) had to remove "ambulance" lettering and any red/blue lenses. They replaced them with clear lenses, and everyone's been happy. Unfortunately, there is a steady demand for clear lenses...

Thankfully, I have conventional relay/diode technology. My failed relay was on a Hoseline circuit board that was part of a 12/120 standby AC system. Some of the proprietary ambulance software & control systems are now obsolete and are a challenge to track down new components, especially if they...

I've run into similar problems with AC systems, most recently a condenser fan relay that someone had tried to use to control both the primary condenser fan and a supplementary condenser fan. The end result was a melted relay. The relay was rated at 40 amps, and had a 45 amp connected load. I...

Pat, my 1999 Medic Master has that kind of cabinetry -- sliding doors for normal access, plus they flip up for larger items and restocking. A friend of mine has a buggy with hinged doors, and he has mentioned that they are always rattling. My sliders stay quiet.
