Hi , just like so of the other guys mentioned go for the dayton rims ( the split rims are dangerous) , I had a steer tire rim fail cut the tube ,the rim was rusted out at the locking ring on inside which you could not see ,luckly was turning slow in front of my firehouse and had spare at my garage and a large floor jack inside the station. 6 new rims and 6 new radials (chinese) tubless on my 54 L Mack 1100 x 22.5 and what a difference in ride and no split rims even they where so called 'Safety Rims'

Really nice Mack L , I want through the same process on my 54 L pumper, www.whitepost.com in Virgina cost about $700.to rebuild the hydrovac, changed all tires and rims to Daytons rims and 1100x20 radials (better ride) after I had a flat on the steer tire ,the locking rim was very rusted out and dangerous,so what would the others look like ? came from snow country Changed the oil filter system from the old sock canister (only filters about 10% of your oil) to a spin-on,you have to make a bracket easy to do , I can send a photo to your phone. also changed the points in dists. to Petronics( electronic) ,must be made for positive ground if that is what you still have. Changed the batteries from 4- 6v to 2 -12 volt

fd2721 send me your mailing address and I'll send you a copy to hinoki22@comcast.net

My email is hinoki22@comcast.net, I have a 54 LS . did a off frame in 2009 to 2011, send your address

or you could weight it empty and full (3750# full if 500gal.)

with a Mack with a 1000gal .tank it would have a double compartment doors on the body & single doors (like yours) for a 500 gal tank ,hope that makes sense. my son has a 71 CF 1000 gal tank . It was purchased new by the fire co we belong to ($42k in 71) .he & his a friend purchased it about 10 years ago. It does not have the original Mack body, the fire co had Grumumn rehab body in the 90's

with 36k miles the engine is not even broke in yet, it looks to be very very clean , many of the Mack of the 70's had bad steel bodies ,looking at yours it looks great. I can tell it has a 500 gal tank most likely, also the rear body is Mack original ( the aluminum over the compartments has rounded corners ). Did you get a good deal on it? Tires look great ,I'm sure the front disc brakes was an upgrade later . take good care of her.

looks like your rear mount ladder & body where not made by Mack but possibly Maxim

try Cal Little in Hummelstown ,Pa. 717-566 -8973

when I had my mechanical fuel pump rebuilt same issue would not start ,we had to pressurize the fuel tank to start (tank was all the way in rear. It could be you have air in the fuel line etc. how about disconnect line from carb and crank over to see what it looks like .

send me your home address, I will make a copy of my wiring diagram from the Mack Museum and mail to you. my email is hinoki22@comcast.net

Also their might be a fuse in line before the terminal box , who knows how electrical things where do in the past, just keep at it and narrow the feed down . Keep the group posted on your findings

Paul said it best ,start with the test lamp probe. their should be a junction box on the firewall (in engine compartment) with the main power switch on the box (terminat) should have power. check the positive & ground connections . It sounds like their is no power to the junction box . I would try connecting a jumper wire (#10 ) from the negative side of battery to the junction box.

where is it now

A Mack Fire Extinguisher is very hard to come by .and usually priced @ 1K, good luck in your find
