[truckdude239]

okay got off work went to start my truck it starts fine sitting there letting it warm up when it cuts off and i mean cut off no power at all! got out and started playing with some wires under the hood next the battery got it started and got it home got to the top of my road and theres my buddy with his 98 jeep wranger sitting crooked i drove up the steert to see if he need up well we waited for an hour for an tow truck to come get him (his rear axle had broke and his tire and drum and axle was sitting in the road.) went to get in my truck it turned over an few times and the the battery slowed down and the the click click click of death. i know i have an drain some where. i know how to pin point it but what are some things to look at? i installed an new voltage reg about an week ago new headlights but 9it seem driving down the road the lights get brighter and dimmer on there own as wel as the cab light. i'm getting up set and am about to order and wireing kit this is an last resort because i really want to get my motor and get it in before wireing anything. i got this truck and thought hye its not going to need alot of work boy was i wrong. i am so glad to have found this site thank you all for the help i've gotten.

Sounds like the voltage regulator or alternator. Take it by a parts store and let them test them to make sure.

i just installed an new voltage reg so maybe the alt is gone bad but i got to find my drain frist

One thing I learned in automotive class was to never assume a new part works correctly. They do come broken, just like anything else you buy. Not saying it's your problem, just don't overlook it.

check the wires on the battery and the little black thing in the fender next to the battery for corosion<sp? i had that same thing happin to me and it was the wires that hook to that little black thingy , what the **** is that thing called anyway ?

Yea, I always say you haven't bought a part unless you've been back to the store a couple of times.

A Junction Block.

the junction box is what i messed with i had put my constant power wire for my cd player to it and the other wires had got loose so i took my cd wire off it and and tigheted everything back up

There's a small wire coming off the pos side to that junction box. Mine was old and worn and wouldn't even crank. Changed the wire and haven't had any problems. Still running the voltage reg and generator. Changing over to alt and new distributor soon.

I had a sticking regulator on my 66 3/4 ton that was draining my battery, replaced it with a new one, same deal! Third one was the charm. If it were me though, I'd definitely swap over to the internally regulated alternator. I looked through the FAQ board and didn't find the post, but I'm sure someone here can chime in with the link.

[truckdude239]

someone told me to check my headlight switch with my new helgon lights they been known to burn up the headlight switch and ground it out draining the battery any ideas on this?

You said that the radio was hooked to the junction block. It has a memory circuit, and that circuit consumes power all the time. Did you guys sit in your truck and listen to the radio, while waiting for the tow truck?

If you want to find the source of the "short", be sure you have a hot battery before starting the following procedure. With the battery disconnected (one terminal only), pull one fuse to eliminate, let's say....the tail lights. When you reconnect the terminal, look for an arc, or listen for the sound that the arc makes when you touch the terminal to the post. If so, then the bad circuit is somewhere else. Keep pulling fuses until you find the circuit that doesn't make the arcing (flash/sound) when you reconnect the terminal to the post.

You might be amazed at what you find.

no i unhooked the radio we where standing outsdide talking to the policew and fire department geez all them showed up for an rear end falling out of his jeep well then again we had all the gear oil out of the rear end on the ground lol.

This is similar to the way I use. I disconnect one terminal, and put a test light between the disconnected terminal and the battery. If there is a draw the light will light up. Then you can pull fuses, when you pull one and the light goes out then you know which circuit it is.
