update
Today i tried a little more trouble shooting. Heres what i did:
Took the following readings:
New battery full charge disconnected 12.90 vdc
connected ignition off 12.78
connected ignition on 12.47
Egine running at idle 12.26
Generator at idle measured across D+/D- 12.60
Engine off after 5 min run, at battery 13.10
At the starter durring starting 11.10
This seems right on to me, everything is close to where it should be(i think).
Where does the DF come into play? There is .39 vdc from it to ground at idle and increases with rpms.
12 vdc across DF/D+ at an idle but as the rpm increases the voltage decreases. WHY?
The next test i started and ran for 5 minutes. Shutdown. Was unable to start again. Tried installing fresh battery, with same result. No start.
All the connections are good and clean. To try and eliminate possibility of high resistance in ground or hot lead, I used one battery for ignition power and one for starting, wired directly to the starter, with a new clean cable.
It seems like she just won't start when warm. The starter is new, but possibly lacking power somehow. I have a big bore kit, does the higher compression require a bigger starter? Or do i have this hot starting problem you guys talk about?? The engine is hardly hot though, after five minutes how hot can it get??
So what do you guys make of this?
