I have a key and a button (under the starboard lazrette as well) to start my Yanmar QM. To start I must turn the key (like a car) then push a button to engage the starter. Does anyone else have this set-up as well?
On to the meat of the question. I am noticing a significant voltage drop when engaging the button. It was getting to the point where I could no longer reliably start the engine. On the advice of an experienced technician, I moderated this voltage drop by replacing the in-line fuse holder on the ignition panel and replacing the connector on the solenoid.
This now keeps my post voltage-drop voltage above the 10 volts needed to get the starter moving but I am wondering if this is typical. Anyone else experiencing this voltage drop on start-up? I am wondering if the push button switch is the culprit as the voltage drop seems to happen when I engage this switch. Though I guess it could be the switch or anything downstream from it.
