Soninihon Posted August 31, 2015 Share Posted August 31, 2015 So this is the second time it happen. When I turn key to start, everything went dead. So I jump battery. Run it for a while to charge. And turn it off. Try to turn it on and same thing. I keep jumping and jumping and still same thing. Then I hear weird noises from the bay. Sounded like alarm was gonna go off but went off due to battery drain. Last time it happen, I was messing with the alarm button on the side of e-break. And then it started working. So my question is, is the factory alarm draining my battery? Or causing it to do something else. If so do I remove the black alarm box under the seat?

k9sar Posted August 31, 2015 Share Posted August 31, 2015 are you sure the battery is good and will accept/hold a charge? Have you checked to make sure your terminal connections are good (jumping will work since you typically place the jumpers on the terminal clamps and not the terminal posts themselves (check voltage on the posts, then check voltage on the clamps) Before looking for the difficult, check the obvious. As for the alarm, I suppose it is possible to have a short but I have had many more occurrences of bad clamps than other electrical issues.

Soninihon Posted August 31, 2015 Author Share Posted August 31, 2015 Thanks for response. I was going to do series of test. And take battery to shop and have it check. I wanted to see if any one else experience same thing as well. Link to comment Share on other sites More sharing options...
k9sar Posted August 31, 2015 Share Posted August 31, 2015 The ones I would first do are to grab a volt meter and check the following: 1. DCV from post to post when vehicle off (should be around 12V) 2. DCV from post clamp to post clamp when vehicle off (should read same as test 1. If not, pull, clean and replace clamps on posts) 3. DCV from post to post with vehicle running (should be around 14V) 4. DCV from post clamp to post clamp when running (should be same as 3 if not, pull, clean and replace clamps on posts) 5. DCV from post to post while trying to start (I believe it drops to 11ish volts on load) 6. DCV from post clamp to post clamp while trying to start. If this drops to near 0 and test 5 does not, you definitely have bad connections After that, take a look at the fuseable links and even feel them after running for a bit. They should NOT be hot. excessive heat here indicates a short Good luck with your troubleshooting and please take the time to followup in this thread with your findings/solution so that others may benefit.

Soninihon Posted September 1, 2015 Author Share Posted September 1, 2015 Ok got her up again. I was going to check for shorts but decided to take battery to store and have it check. Battery was still good. They clean out the corrosion a bit. As I put it back in, I just say "screw it, I'll just give it a try again". Thinking it won't start, I was going to spend the evening trying to find the short. But then BOOM, it started! Seems like the clamp for the battery was loose and I didn't realize it or the corrosion was in the way. Well thanks for the help guys. Maybe this post will help others who have same problem.
