Muncher Posted August 29, 2021 Share Posted August 29, 2021 So a while back I had a electric draw and it turned out to be my brand new battery. I got it replaced and it's been fine for a while but now today and yesterday I went out to start it and it's completely dead. Should I assume it's the battery again? I had it running yesterday for a whole so what could even kill it completely like that in a day? Link to comment Share on other sites More sharing options...
zomeizter Posted August 30, 2021 Share Posted August 30, 2021 Sounds like you still got a parasitic draw, check your glove box light, that kicked my @$$ a while back... Link to comment Share on other sites More sharing options...

I had actually taken my glove box light off and it was just sitting on the bottom of it so it was on all the time. I screwed it back in and I'm going to check back in on that tommrow Link to comment Share on other sites More sharing options...

Minuit Posted August 31, 2021 Share Posted August 31, 2021 It almost certainly wasn't the battery the first time, and it's still almost certainly not the battery. You need to find the draw the hard way - that is, put an ammeter on one of the battery terminals and disconnect things until the draw goes away. Like they said, it's probably the glove box light. That has to be properly adjusted for it to go off when the glove box is closed. If that's the case, the draw would go away when the "DOME" fuse is pulled.

I'm going to check in a minute and see if the battery's at all dead Link to comment Share on other sites More sharing options...

JustEmptyEveryPocket Posted August 31, 2021 Share Posted August 31, 2021 What scale were you in? 0.2 amps is a lot of draw for a battery and could make it go dead sitting a day or so. You should be trying for ~50 milliamps or so. That is 0.05 amps. Though you should take that number with a grain of salt. Regardless, it should be quite low. @Ωhm, do you know what the acceptable draw is for a Renix? Link to comment Share on other sites More sharing options...
Minuit Posted September 1, 2021 Share Posted September 1, 2021 The group 58 battery that's specified for these trucks have about 35 amp hours of capacity on average before the battery is fully discharged to 10.5 volts. A 0.2A draw would kill such a battery in a week, which is completely unacceptable. My '89, although most of the interior electronics are gone right now, starts after months of sitting. Also - alternative way to check for a parasitic draw if the circuit you're testing has a fuse with exposed test points at the top: put your meter in DC volts mode on its lowest scale, and probe across each fuse. Any fuse that reads a voltage has a parasitic draw. This doesn't tell you how big the draw is, but it will quickly tell you where it is. When doing this on the interior fuse box, make sure to do something to push the door ajar switch in so the dome lights don't come on. Link to comment Share on other sites More sharing options...

No, I do not know, but as mentioned above 200mA (0.2A) will kill any battery. My guess would be less than 20mA depending on type of battery.

Muncher Posted September 1, 2021 Author Share Posted September 1, 2021 this truck doesn't happen to have a ash tray light, does it?It does I replaced it with a led. It's started up the past few days again though fine after tightening my battery cables and re installing the glove box light Link to comment Share on other sites More sharing options...
