lights that dim when a system is cranked is a sign that the ground return to the battery is crapola, now the only way to fix it is find out, with a multimeter and some time, where the ground issues are, in most cases it will be the amp ground. plus a lot of bunnings, DIYer's, dont upgrade the battery ground. if your going to run a 4awg power cable to the amps then you also need a 4awg ground cable added, your taking power out, but on what is it going to return? on that shitty little factory ground cable?
it aint rocket science, but looks like all those mentally challenged people seem to go out and buy this or buy that to try and fix something that is sooooooo simple its just they dont like to listen to people in the know, but rather opt to listen to the salesman that wants to offload a shiny new cap or chrome plated alternator. that does also depend, but if you go up towards the top of this thread you will see where ive mentioned when a cap is needed as a rule of thumb.
