Get the charging rate and battery tested. If charging is insufficient or battery is weak, the condition would occur.

Poor grounding circuit connections or insufficient contacts between battery terminals are things to check.

The site has just been through a major upgrade and there are some teething problems so hope it is resolved soon. I am having difficulty navigating through the site and getting back to questions I answered is a headache for now.

I made a reply but seems it did not get through.

This site has just been through a major upgrade and everything is different from previous version so I am having difficulty navigating through. Hope problem is resolved soon.

There are 2 things that can cause the symptoms described.

1. Charging rate. Get the alternator and battery tested.
2. Wiring connections. Bad ground circuit and poor bettery terminals connections can cause the symptoms described.
