Slow Cranking IDi

[riotwarrior]

Db electrical has starters new from 65 bucks...can u afford to rebuild? Their 4kw one is 175 bucks roughly...end your startjng issues and buy new with warranty.

If a winding is bad you wont know until you are done the rrbuild and it still cranks slow.

buying a used starter is a crap shoot...may work well..may not...

In your original post, you say you replaced ONE battery.... because it was ??? doing what?

On a two battery system... if one goes bad.. it will take down the other battery... I strongly suggest you load test BOTH batteries you currently have..

I'll make a bet you have at least one that is not holding full charge under load because it has a weak cell or two.. thus slow crank speed. Even though both are now new. I've had new batteries fail off the shelf lately...

It's an easy check.. only takes couple minutes.. but could save you grief replacing a starter that in OK, just needs more available amps than a weak battery is putting out..

Let us know how that works out..

Sorry, my post wasn't clear... Check your NEW batteries with a load tester.. It is possible one of the new batteries has a bad cell and isn't making full power..

I've this happen to me recently.. brand new battery, meter says it has a 12.67 Volt charge.. but when I load test it.. it dropped volts like a rock in water.. had an internal fault in one cell.

riotwarrior db electric seems to be priced well but couldn't find the 4kw only one seems available is the original Mitsubishi

Yaah might be take a 2nd look , I have seen things fail out of the box before

Here's the deal with a 2 battery system. This applys to ALL 2 battery systems. A battery slowly drops amps and volts as it fails. So it draws those amps and volts from the higher voltage and amp battery. It will flow to the lower charge battery like water flows from a higher body of water to a lower body of water. Once they are both even in charge or fill they rest like that. This is the reason we REPLACE BOTH BATTERIES at the same time. Sadly it can become costly. No matter what you do about load testing a "good battery" and replacing an bad battery. Eventually you will be replacing another bad battery because they do not fail at the same rate.
