Well battery not going flat anymore as such.
been driving it for three days now. this morning cranking fine, glow plug light was on for a very short time then flashed after i started to turn the engine over.
checked under the bonnet nice 12.4 volts across the battery after two attempts at starting and being a hot day I used the full open option.
Thought it might be flat again but turning the engine over with full force, connected the heavy duty booster pack and still nothing. however the voltage dropped to just under 12 volts when the glow plugs were running. as soon as the clicked off it was back to 12.3. i tested with the booster on and it was a little higher like 12.5 dropping to 12.1 12.2 still the same turning force
By the way my booster pack is a 069 battery that is used for jumping all the time and it has just been on a charge yesterday with 4AWG arctic gold cable High ampage cable.
Checked the voltage at the glow plugs, and there only showing 10 volts climbing to about 10.8 volts then cutting after the normal time, there staying on after the engine is being cranked. so connected the booster to the glow plugs and engine earth and took it off after around 4-6 seconds eg got them hot,
Ran round and turned the key and brum it started, no problems no issues,
There is one other issue that may be related its holding back just a little if you try to drive idling at 3000 rpm, its fine below and above this, i think this may be the engine temperature sensor from other posts but have not yet been able to check this.
Is there a common fault with this curcuit or a faulty resister or is it a diode. please advise.
By the way had it on the new snap-on solus pro and the only faults were the dashboard fault of low battery this has been cleared and has not come back.
Please help me find this fault two weeks now.
