M101A2 Lights

[Randyw]

So I got my new to me M101A2 trailer cleaned up and hooked up to my 1008. After connecting the lights and checking to make sure they worked I noticed that the lights seem very dim. Everything works with the lights it just they are not very bright. Is this normal? Or is there some way to fix the problem?

 

[Evil Dr. Porkchop]

Check the bulbs, there is a chance they are 24v instead of 12v.

The 101 has 24v bulbs that is powered though the 08s 24v system, look for a bad ground.

 

[Randyw]

Shouldnt they be 24v if its conected to my 1008? My truck still has 24v volt system it has not been changed to 12v.

 

[Evil Dr. Porkchop]

The truck has 12v lights and sends 12v to the trailer in its stock configuration.

The only thing on the CUCV's that's 24v is the starting system the rest of the truck is 12v.

 

[Randyw]

How do I know if the bulps are 24v?

 

[Evil Dr. Porkchop]

It might say 24v on them. If the part number is 1683 on the larger one and 623 on the smaller ones they are 24 volt.

 

[Recovry4x4]

Check the numbers on them or be proactive and just replace them.

 

[Randyw]

Ok I will just go ahead and change the bulbs it cant hurt to put some new ones in there. Where can I get the 12v bulbs for the trailer?

 

[Evil Dr. Porkchop]

At your local auto parts store. I use 1156s and 67s.

 

[73m819]

WRONG, the military trailers hooked to cucvs use 24 volt bulbs, you can hook these trailers to ANY MIULITARY TRUCK and the lights WILL WORK AND NOT BLOW THEM OUT by running 24v though a 12v bulb

 

[Randyw]

I pulled the bulbs and numbers are 1683 on the large bulb and 1251 on the small bulb. 73m819 I was thinking the same thing. These trailers were used with these trucks and 1009's when they were in service so I figured it would work. But I may be wrong. I also noticed two other bulbs on the bottom that I am not getting anything. I am getting running lights, brake lights, and signal lights. are the bottom bulbs back up lights? because im not getting back up lights when in reverse.

It might not hurt to clean the grounds.

Those are 24v bulbs. CUCVs have 12v lights. The bottom bulbs are for the blackout lights.

 

[Randyw]

Got ya on the black out lights. I turned them on and the bottom bulbs work. So if I change the bulbs to 12v this will cure the problem with the dim lights?

It should.

 

[Randyw]

Thanks Evil I will try that and see what happens.

On the 09 as with ALL cucvs has 12v for the vehicle , the trailer plug supplies 24v to the trailer lights
