easystart

[TJAGAIN]

sorry to bring this up again, after all the good advice i changed my battery and yes started first time but on checking my easystart on the perkins 4108 found no power to the unit. what do i check next ? is it wired through some kind of relay , looks as if it goes to what looks like a small alloy box with spade fittings . any help as to how to proceed?

Normally it is wired via a single lead (+ve) from the ignition switch. There is a position that activates the glow-plug before you then switch to start position. That is with the original start panel.
Many boats have not got the panel and it is common for the lead to go to a push to make button, (power taken from the battery +ve supply to switch panel). The -ve side is covered by the engine -ve return to battery.
Example : Our boat lost it's Perkins panel many years ago and has a simple one instead. Toggle switch that switches on power to :

a) Alternator exciter circuit
b) Starter push button
c) Cold-start push button

So sequence to start is :

Switch on toggle switch to provide power to panel. Press and hold cold-start button till wisp of smoke from air-intake, often a pop can be heard as the diesel ignites on the glowplug. Then let go coldstart button and immediately press start button.

Note that the current carried by the coldstart is significant and a suitable sized lead should be used. You also need a supply of diesel to the item as ignition fuel. It only requires a small drop.

They often go through a relay due to the power requirement. Check that power is coming from the cold start button, (or ignition switch cold start position). Sounds as if the alloy box is an old relay. Check that power is going to one of the small leads at the box when the cold start is activated. If yes then the fault is likely to be the relay. If so you can get a replacement from the local car shop. I used a starter solenoid for mine but you can get relays that take up to 70 amps if you prefer.

There's no need for a relay if suitable push button and lead is used.
Ours works from a Horn push putton salvaged from an old Marine Switch panel and lead is one insulated wire core from a twin and earth domestic cable. Both appear to do the job and have lasted many years.

many thanks chaps i will have another revised look at it
