Change over to tubeless 1100.20. I did all four on back of my 52 L85 and it was night and day difference. Truck rides so much better. I found all four rims and pretty new tires for $100 on Craigslist
-
I use truck almost weekly during season with shows, funerals parades, taking my kids for ride. Sadly she’s put away now till weather breaks
-
Got the old girl running again. Used a block diode rectifier in place of original. Charging at 14v and ran for 3 hours with lights and sirens for Christmas parade and she ran great. Thanks to everyone’s help helping me work thru the issues
-
Definitely added larger tank which is very common for rigs from my area when they go north or south. We are a complete hydrant district. I’ll get some info for you to answer some of your questions
-
I can find any info you want. I know the company wanted to buy it back but maybe the right people weren’t in contact with each other
-
I was in its original firehouse doing a standby for Tarrytown last weekend. All of their apparatus was always beautiful cared for rigs
-
The rectifier was bad but now changed out.
-
Replaced rectifier with diode rectifier Alternator was cleaned up and checks good, voltage regulator good, grounds good and ran a few new ones while I was up in there, still charging at 18 volts 🤦♂️
-
That’s what I was thinking. Old one is positive ground and mounted right to metal bracket on side of motor
-
Rectifier is gone. Also confirmed with Vineland electric in jersey. I had a feeling it was. Can’t thank you guys enough again. I take every you say into account and will use in future as well
-
Leaving original alternator is there anything that can go in rectifiers place. That things is way outdated and dangerous. I have seen a few rigs replace with what I was talking about a 3 phase block rectifier that seems to work. Even if temporally till I can save some money to make better upgrades
-
Mrmack my battery is few months old. Load tested perfect sealed battery
-
Written on my rectifier in marker says Bridgeport fire shops. 1984 replaced came off old engine 6. The old engine 6 was a late 40’s L model Mack
-
I definitely smelled rotten eggs when she started to die on me. Felt battery and it was warm but I don’t believe the smell was coming from that. Does the rectifier give off that kinda smell as well
-
I am gonna test tomorrow. I’m just asking if that’s something that can be used in event it’s bad .
-
So can I use a 3 phase block rectifier that’s rated at 100amps 1600 volts to replace the rectifier is that shows bad ?
-
I appreciate your input very much. Changing a motor is nothing to me. Some wires and I’m lost. Took me a while just to understand positive ground because everything I’ve ever learned was opposite. I’m eager to learn and care for these rigs for the future
-
Two different volt meters so yes. Everything was fine. Was driving home from show when it happened. Changed voltage regulator and it’s still happening
-
Thank you for response. I have braided ground straps from frame to motor. And frame to body. And they are in really good shape. I used dremel tool with wire brush and cleaned all terminals on alternator, regulator, battery and ground connections. Replaced field ground between alternator and rectifier, replaced field wire between alternator and voltage regulator. When I turn ignition on you can hear voltage regulator click. Starts right up then voltage climbs to 17-18 volts within a few seconds.
-
I’m trying my best to learn and figure this out. I’m asking so I can learn. I’m not just guessing, I’m asking from people who have way more experience than me. I’m doing this work alone in my back yard and don’t have endless money on hand to hire people. I appreciate the help everyone has gave so far
-
I understand what you are saying. If rectifier is bad could that cause my overcharging? The Regulater is replaced all grounds cleaned and checked, field wires clean and check out. Not sure what else could cause the 18volt overcharge. I appreciate all your help so far
-
Gonna have the alternator gone thru and cleaned up by a shop. When I opened back where field is there was a lot of dust and junk. It spins free with no noise hopefully it comes back good. Now I think I need to replace rectifier too it’s 42 years old. Anyone have one or know how to replace it with something else that can work? Frame to motor ground is good and cleaned up some other wires I didn’t like the look of.
-
The one field wire went to bolt on rectifier I made replacement wire and fixed that. The other went to the F on my regulator and I ran a new wire between them as well. So both of those are replaced.
-
If the other is field wire I will replace that too it’s pretty funky and looks like someone patched it a few times
-
The 2nd picture has two wires off back. One goes to rectifier which I believe was a ground to it, is the other the field wire? The rectifier wire was in bad shape so I made a new wire in its place
